Efficient low-boiling-point co-solvent systems were developed for the oxidative depolymerization of lignin to high-value platform chemicals, mainly vanillin and lactic acid, using molybdenum (Mo)-based solid oxide catalysts and hydrogen peroxide (H2O2) oxidant. The co-solvent, designed with the matching Hansen solubility parameter (HSP) values to lignin, facilitated efficient solvation of lignin. Various factors, including co-solvents, catalyst supports, H2O2 concentrations, and active metals, were detailly investigated. Optimal yields of total liquid products (EA oils: 19.8 %) were obtained in water-tetrahydrofuran (H2O-THF) co-solvent systems, increased by 61.0 % compared to that of the sole aqueous solution, employing a MoO3/Al2O3 catalyst. Additionally, the oxidized lignin (O-lignin) or EA oils was analyzed using UV-vis, CHN, GPC, and FT-IR techniques. Results indicated that the co-solvent system remarkably inhibited the repolymerization of lignin fragments, and enhanced the oxidative cleavage of lignin side chains. Lastly, a hypothetical mechanism explained the reaction pathway of lignin depolymerization in co-solvent systems.

SPRINGER
The catalytic transesterification of vegetable oil over heterogeneous catalysts is an effective approach for biodiesel production. To elucidate the role of MgO in catalyzing this reaction, several CaO-MgO catalysts with various Mg/Ca ratios were synthesized by co-precipitation. The catalysts were characterized by BET, XRD, SEM, HRTEM, FTIR, TGA, CO2-TPD, O-2-TPO, and in situ DRIFTS. The catalytic performance in the transesterification of soybean oil with methanol was evaluated in a stirred batch reactor. The results indicated that the synthesized pure MgO had weak basic sites and poor pore structure, showing the lowest activity. The added Mg in the CaO-MgO composites was present in both doped and supported forms. The doped Mg reduced the lattice spacing of CaO, improved the intensity and number of basic sites, and enhanced the activity of catalysts, while the supported Mg hindered the diffusion of reactants to the basic sites. The amount of the doped Mg showed a maximum value due to the solubility nature of CaCO3 and MgCO3. 1Mg3Ca (Mg/Ca=1/3) exhibited the highest activity with a biodiesel yield of 92.28% at 60 degrees C for 2 h. CaO is sensitive to water and CO2, forming hydroxides and carbonates. The supported MgO with a low porous structure well protected the basic sites from contamination. High-temperature treatment is an effective method to remove the contaminates and the removal temperature increases in the order of H2O < Mg(OH)(2) < Ca(OH)(2) < CaCO3.

ELSEVIER SCI LTD
A heterogeneous molybdenum (Mo)-based oxide catalyst system in combination with hydrogen peroxide as an oxidant was developed for oxidative depolymerization of lignin to yield high-value platform chemicals in a nearly neutral aqueous solution. The impact of various reaction conditions, including the ratios of H2O2 and/or MoO3/Al2O3 catalyst to lignin, reaction temperature and duration, and lignin concentration, were investigated in a batch system or a continuous flow fixed-bed system. The structural changes between dealkaline lignin and the recovered lignin (O-lignin and M -lignin) were analyzed using UV-vis, FT-IR, and GPC techniques. The com-bination of MoO3 and H2O2 resulted in a superior peroxo complex, promoting the formation of vanillin and lactic acid. The medium and weak acid feature of MoO3/Al2O3 catalyst induced the highest vanillin yield (5.6%) and the selectivity (86.9%) of main platform products. However, the highest yield of lactic acid (3.4%) was observed on MoO3/SiO2 with more weak acid sites. Hypothetical formation mechanisms for vanillin and lactic acid were proposed based on the depolymerization of lignin model compounds.

A novel alkaline ionic liquids N-allylpyridinium hydroxide ([APy]OH) was successfully designed and developed as a catalyst and co-solvent with ethylene glycol in the continuous depolymerization of lignin. Various reaction conditions, like lignin concentration, water content, and reaction temperature, were investigated under atmo-spheric pressure. Ethylene glycol was used as main solvent and repolymerization inhibitor of the aldehydes produced. The combination of [APy]OH and alkali metal salts exhibited a good synergistic effect for lignin depolymerization. Then, the depolymerization of three different lignins, including dealkaline lignin (DA-lignin), alkaline lignin (A-lignin), and sodium lignosulfonate (S-lignin), were also studied. S-lignin exhibited the highest yields of total liquid products (21.3 %) and aromatics (10.7 %). The change in lignin structure after depoly-merization was observed by means of FT-IR and DTG-DTA techniques. Lastly, a hypothetical pathway for lignin depolymerization was proposed based on the catalytic results of lignin model compounds (LMCs) with different linkages.

ENVIRONMENTAL PROGRESS & SUSTAINABLE ENERGY
WILEY
A novel, eco-friendly direct graphite exfoliation method was developed using 1-allyl-pyridinium-based ionic liquids (ILs) under microwave irradiation. Exfoliated graphene comprising a few layers was prepared from graphite using 1-allyl-pyridinium nitrate under 300 W microwave irradiation for 10 min, which was characterized by X-ray diffraction, Raman spectroscopy, and X-ray photoelectron spectroscopy. Density functional theory calculations indicated that the combination of the cations and anions in the ILs led to improved adsorption on the graphite surface. High-power microwave irradiation can also allow cations to intercalate easily between the graphite layers and increase the efficiency of graphite exfoliation. Solid acid catalysts were prepared from exfoliated graphene via oxidation and sulfonation. The catalytic activity was evaluated for the saccharification of cellulose, where the highest monosaccharide yield of 15.9% was obtained after 24 h at 140 degrees C with a cellulose/solid acid catalyst/water ratio of 0.1/0.05/3 (g/g/g). This performance was superior to that of several commercial catalysts. The magnetic solid acid catalyst which was prepared to facilitate separation from cellulose residue showed constant durability in three activity tests.

A series of CoMo/A1203 catalysts with various Co/Mo mole ratios and a series of CoMo/TiO2-A1203 catalysts supported on TiO2 coating Al2O3 were prepared. The effects of Co/Mo mole ratio and TiO2 loadings on Al2O3 on hydrodeoxygenation (HDO) and decarboxylation/decarbonylation (DCO) in the hydrotreating of palm fatty acid distillate (PFAD) were investigated. The catalysts were characterized by BET, XRF, pulse NO chemisorption, and H2-TPR. The maximum yields of n-C16 and n-C18 was observed at Co/Mo = 0.05 for the CoMo/A1203 series, and the yield of n-C15 and n-C17 was increased at Co/Mo > 0.05. CoMoS phase apparently has both HDO and DCO activities. CoMo(0.05)/Ti(20)-Al showed the maximum yields of n-C16 and n-C18 due to the formation of TiMoS in all catalysts. TiMoS phase may be formed by adding TiO2 on Al2O3 and promotes the HDO reaction, but not isomerization or cracking.

We prepared activated carbon-based solid acid catalysts derived from coconut shells via chemical activation with phosphoric acid under air and subsequent sulfonation. Their catalytic activities were evaluated in the saccharification of cellulose, and the parameters required for the activation and sulfonation processes were investigated. A catalyst activating temperature of 400 degrees C was found to be optimal, and the catalyst treated with chlorosulfuric acid exhibited a similar monosaccharide yield to that treated with fuming sulfuric acid. The prepared catalysts were characterized by various analytical techniques. The catalysts exhibited high specific surface areas and micropore volumes but low external specific surface areas. The catalysts had high contents of acidic functional groups when low activating temperatures were employed. For these catalysts, the surface chemical structure had a more dominant effect on the catalytic activity than that caused by the porous texture, while high acidic group contents led to high catalytic activities.

Graphene oxide, which exhibits extraordinary acidic properties and a high theoretical surface area, is a good candidate for the catalytic transformation of biomass resources to valuable chemicals and biofuels. In this study, graphene oxide was prepared through various graphite oxide exfoliation methods, including sonication, microwave irradiation, and freeze-thaw cycling, and the activity of the prepared catalysts was evaluated in the saccharification of cellulose. The results indicated that graphene oxide prepared via these methods exhibited superior catalytic performances compared to graphite oxide; however, no significant difference in the catalytic activity of the graphene oxide catalysts was observed based on the exfoliation method used. Therefore, we proposed that thinning of graphite oxide improves its catalytic activity by increasing the contact efficiency between the substrate and the catalyst; however, this is not dependent on the exfoliation method used to prepare the graphene oxide.

RSC ADVANCES
ROYAL SOC CHEMISTRY
A series of Ru and Ni supported catalysts were prepared and their catalytic performance was evaluated in the steam reforming of xylenes. The effects of active metals, active metal loading sequence, and the calcination temperature of the support on the catalyst activity and stability were investigated. The bimetallic 2Ru -> 15Ni catalyst shows much higher activity and stability than the monometallic 2Ru and 15Ni catalyst owing to the synergic effect of Ni and Ru. The 2Ru -> 15Ni catalyst has the least coke deposition owing to its high conversion performance and much less coke precursor being formed on the catalyst surface. After decoking, most of the small-sized pores cannot be recovered because of the pore collapse under severe hydrothermal conditions. o-Xylene has the lowest reactivity due to electronic and steric effects. Besides the steam reforming reaction, demethylation and C-C cracking are also observed, forming benzene and toluene. The catalyst with a loading sequence of 15Ni -> 2Ru shows high activity at low temperatures (550-600 degrees C), but undergoes an activity drop at high temperatures (625-650 degrees C) because the Ni sintering at high temperatures greatly affects the state of Ru on the catalyst. The catalyst with a loading sequence of 2Ru -> 15Ni has an advantage at high temperatures owing to its better sintering resistance. The simultaneously loaded 2Ru <-> 15Ni catalyst shows the lowest activity. The high calcination temperature of the support enhances the catalyst stability by eliminating the small-sized pores before reaction; on the other hand, the elimination of pores decreases the dispersion of the active metals. The 2Ru -> 15Ni catalyst calcined at 1000 degrees C balances the active metal dispersion and resistance to sintering under severe hydrothermal conditions, showing the best activity and stability. The catalyst calcined at 1000 degrees C has the best coke resistance with only 0.166 g g(cat)(-1) of coke formation after the 24 h durability test. The DTG results indicate that the carbon formed on the catalysts is mainly graphitic carbon.

A process of chemical activation with phosphoric acid from coconut shell in air to produce activated carbon was developed. The effects of various preparation parameters on the porous texture and surface characteristics were investigated by means of the nitrogen physisorption, Fourier transform-infrared spectra (FT-IR), and X-ray photoelectron spectroscopy (XPS). The adsorption capacities of activated carbon for chromium, lithium, and cesium were also investigated. The surface modification of activated carbon using nitric acid was performed to enhance the adsorption capacities, and the relationship between the adsorption capacities and the surface functional groups was investigated. The oxygen-containing functional groups on the surface of an activated carbon played a more important role than its textural structure in adsorption of metal ions, especially cesium ion.

Two series of supports, SAPO-11 (Si/Al: 0-0.4) and alumina-coated SBA-15 (Al2O3: 0-20 wt %), with different pore structures were synthesized. Subsequently, the PtSn bimetallic catalysts supported on these supports were prepared using a co-impregnation method and were characterized by N-2 adsorption measurement, pyridine-adsorbed Fourier transform infrared, CO chemisorption, and H-2-TPR. The catalytic performances of the catalysts in the hydrotreatment of palm fatty acid distillate (PFAD) were tested using a fixed-bed flow reactor system. PtSn/ALPO-11 (Si/Al: 0) showed the highest n-C-16,C-18 selectivity (66.4%) among the SAPO-11-based catalysts, and PtSn/20A1/SBA-1S (20% Al2O3) showed the highest n-C-16, n-C-18 selectivity (61.5%) among the SBA-15-based catalysts. It was found that higher Bronsted acid content on the catalyst showed higher isomerization selectivity. Based on the comparison of PtSn/SAPO-11 (0.1) and PtSn/10Al/SBA-15, the mesoporous structure favored hydrodeoxygenation activity. Also, it was suggested that Bronsted acid affected the structure of active sites and highly dispersed Pt favored formation of n-hexadecane and n-octadecane.

A series of PtLa chi/SO42-/ZrO2 catalysts, where chi is the atomic ratio of La to Pt of 1, 3 and 6, were prepared and used for the catalytic depolymerization of alkali lignin with ionic liquids in a continuous flow fixed-bed reaction system. Compared to the SO42-/ZrO2 catalyst, the introduction of Pt and La2O3 significantly enhanced the catalytic activity in alkali lignin depolymerization. According to the characterization results of the catalysts obtained from N-2-physisorption, FT-IR spectra of CO or pyridine adsorption, and XPS and TEM analysis, the introduction of Pt and La2O3 resulted in the highly covalent character of sulfate species on the catalyst surface and strong interactions between Pt and La2O3, which led to an increase of the number of Lewis acid sites for PtLa chi/SZ catalysts. The PtLa3/SO42-/ZrO2 catalyst showed the highest yield of phenolic compounds (28.7%) at 210 degrees C. Furthermore, based on the results of two model compounds of lignin in pretreatment and reaction units, the synergistic effect of ionic liquids and catalysts was also elucidated and a hypothetical reaction pathway of lignin depolymerization was elucidated.

Two-Step Saccharification of Rice Straw Using Solid Acid CatalystsSukma, Luh Putu Pitrayani; Wang, Xiuhui; Li, Sen; Thanh Tung Nguyen; Pu, Jianglong; Qian, Eika W.
INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH
AMER CHEMICAL SOC
To establish an efficient bioethanol production system, a solid-acid catalyst-based saccharification of rice straw in two steps was developed. It was rarely concerned so far that many biomass species contain a significant amount of nonstructural carbohydrates (NSCs, free sugars and starch). NSCs, including hemicellulose, are readily hydrolyzed but also susceptible to overreaction with byproducts. In the developed process, the first step is intended to effectively hydrolyze the significant sugar source of NSCs and HC in rice straw under a mild condition, and the second step is addressed to hydrolyze the cellulose in the residue obtained under a harsh condition. For each step, several catalysts were screened and reaction condition were investigated. For the first step, an appropriate catalyst was Amberlyst 35 Dry, at 130 degrees C for 30 min in which high yields of C6 monosaccharide, 47.2%, and C5 monosaccharide, 10.8%, were obtained. For the second step, the most active catalyst was a sulfonated mesoporous carbon that provided a maximum yield of C6 sugar (52.5%) at 220 degrees C for 0 min. A test with the sequential two-step saccharification provided a 65% yield of sugars. From the investigations, the most studied modified pathways of dilute-acid catalyzed hydrolysis of HC and cellulose were also likely to occur with a solid-acid catalyst with an additional pathway of direct hydrolysis of NSCs to C6. To support the observed phenomena, the characteristics of the RS before and after saccharifications were analyzed using SEM and XRD. Thus, this process represents a method to increase the cost-effectiveness of bioethanol production system in an environmentally sound way.

The catalytic depolymerization of alkali lignin dissolved in a mixed solvent of ionic liquid (N-allylpyridinium chloride, [Apy]Cl) and water, with ZrO2/SO42- or Pt-ZrO2/SO42- catalyst, were performed in a continuous flow fixed-bed reaction system at low temperature (from 150 to 210 degrees C). The yields (carbon-based) of total products and phenolic compounds catalyzed by ZrO2/SO42-, which increased with increasing temperature, were 30.6% and 13.4% at 210 degrees C, respectively. Furthermore, the addition of platinum to the ZrO2/SO42- catalyst enhanced the depolymerization of alkali lignin. In the case of Pt-ZrO2/SO42-, the yields (carbon-based) of total products and phenolic compounds reached 44.9% and 18.7%, respectively, at 210 degrees C. Additionally, [Apy]Cl readily dissolved lignin and served as a medium for lignin depolymerization, which improved the reactivity of lignin for the use in the continuous flow system at low temperature.

MICROPOROUS AND MESOPOROUS MATERIALS
ELSEVIER SCIENCE BV
Ti-inserted ordered mesoporous silica SBA-15 (Ti-SBA-15) synthesized by original microwave-assisted method as a support was used to prepare CoMo catalysts to develop a new catalyst with high hydrodesulfurization (HDS) and controlled hydrodearomatization (HDA) activities. The activity tests of catalysts were carried out by using a pressurized fixed-bed flow reactor. 4,6-Dimethyldibenzothiophene (4,6-DMDBT), 1-methylnaphthalene, and phenanthrene were used as model reactants in HDS and HDA, respectively. CoMo/Ti-SBA-15 catalyst showed about 1.35 times of HDS activity and half of HDA activity of CoMo/SBA-15 catalyst. The results of XRD, FT-IR and Si-29-NMR reveal that titanium was successfully inserted into silica framework of SBA-15, and the SBA-15 mesoporous structure was maintained after insertion of titanium. The reduction of molybdenum from Mo6+ to Mo4+ readily occurred with incorporation of titanium, resulting in an increase in Mo4+ species and CoMoS phase on sulfided catalysts. This enhanced the HDS activity of CoMoTiSBA15 catalyst. Moreover, the presence of Ti3+ on CoMo/Ti-SBA-15 was observed, suggesting that TiMoS was formed and played a role as new active sites. CoMoS active slabs with shorter length and higher stacking layer were formed on CoMo/Ti-SBA-15 comparing with CoMo/SBA-15, resulting in the low HDA activity of the former.

ELSEVIER SCIENCE BV
To obtain a novel catalyst with high resistances to metal sintering and coke formation in the steam reforming of acetic acid, a series of nickel core-shell catalysts were prepared. The effects of the shell thickness, shell species and core particle size on the catalytic activity in the steam reforming of acetic add were investigated. The prepared Ni@SiO2, Ni@Al2O3, Ni@CeO2 and Ni@TiO2 catalysts were characterized by BET, XRD, H-2-TPR, DTG and HRTEM. The prepared core-shell catalysts showed high resistances to nickel sintering, owing to the protection of the shells, in comparison with bare nickel particles. Ni@SiO2 with a thin shell showed a higher activity than the corresponding catalyst with a thick shell due to the thin silica shell allowing the facile diffusion of reactants and products. Because of the important role of the support in steam reforming reactions, the shell species greatly affected the catalytic activity in the steam reforming of acetic add. It was demonstrated that an alumina shell was best suited for the steam reforming of acetic acid among the studied shells owing to its excellent water dissociation ability. The Ni@Al2O3-i catalyst showed excellent activity with an almost complete conversion and a hydrogen yield up to 91.2% at 750 degrees C due to its much smaller nickel particle size. The coke formed on the spent core-shell catalysts after the activity tests was mainly graphic carbon, and the Ni@Al2O3-i catalyst exhibited a superior coke resistance with the smallest amount of formed coke. HRTEM results of Ni@Al2O3-i indicated the alumina shell had a high hydrothermal stability and further confirmed the high sintering resistance in the steam reforming of acetic acid.

A series of mesoporous carbon-based solid acid catalysts were prepared using tannic acid (C76H52O46), a polyphenol compound, as starting carbon materials and SBA-15 as silica template. The tannic acid catalysts were characterized by use of N-2 Adsorption-Desorption Isotherm, XRD, FTIR, XPS, and titration method. Phenolic hydroxyl group with weak acidity was confirmed as main functional groups in these catalysts based on characterization using FT-IR and XPS. The catalysts were tested in saccharification of cellulose. Effects of different preparation parameters of catalyst were correlated to its saccharification activity: (a) oxidation using H2SO4 was important factor determined the high catalytic activity of catalysts, proved by comparison of catalytic activity of catalysts after treatment in concentrated H2SO4 and parent materials lacking the functionalization, (b) higher carbon coating also promoted good catalytic activity since it has higher relative percentage of acid functional groups based on XPS measurement, and (c) catalyst that treated by short oxidation time (2 h) could exhibit higher catalytic activity compared with catalysts that treated by longer oxidation time. With a ratio of catalyst/substrate: 0.5/1 (g/g) at 180 degrees C for 1 h, glucose yield and conversion of 31.45 and 53.86% could be obtained.

PERGAMON-ELSEVIER SCIENCE LTD
A series of Ni@Al2O3 core-shell catalysts with ceria added to the surface of Ni nanoparticles or inside the alumina shell were prepared, and the effect of ceria addition on the performance of the catalyst in the steam reforming of acetic acid was investigated. The prepared catalysts were characterized by BET, XRD, HRTEM, H-2-TPR and DTG. The addition of ceria to the surface of nickel nanoparticles greatly enhanced the activity of catalyst owing to the presence of the mobile oxygen, which migrated from the ceria lattice. Among the prepared catalysts, the Ni@Al10Ce catalyst showed the highest activity with a conversion of acetic acid up to 97.0% even at a low temperature (650 degrees C). The molar ratio of CO2/CO was also improved due to the oxidation of CO by the mobile oxygen into CO2. The coke formation on the core-shell catalysts was significantly inhibited by the addition of ceria to the surface of nickel nanoparticles due to the oxidation of carbon species by the mobile oxygen in the ceria lattice. However, the Ni@Al10Ce-a catalyst with ceria added to the alumina shell showed a low activity and the formation of a large amount of coke. It is suggested that only the ceria in close to the Ni surface has the promoting effect on the catalytic performance of the Ni@Al2O3 catalyst in the steam reforming of acetic acid.

Evaluation of Reactivities of Various Compounds in Steam Reforming over RuNi/BaOAl2O3 CatalystPu, Jianglong; Toyoda, Takashi; Qian, Eika W.
ENERGY & FUELS
AMER CHEMICAL SOC
Hydrogen production via steam reforming of bio-oil is a potential method to reduce the dependence on the conventional fossil fuels. To investigate the reactivity of bio-oil and its difference with gasification tar and conventional fossil fuels, the steam reforming of various compounds (benzene, toluene, m-xylene, m-cresol, n-hexane, cyclohexane, 1-propanol, and acetic acid) was conducted in a fixed-bed flow reactor at various temperatures over a high-performance RuNi/BaOAl2O3 catalyst. 1 As a whole, the reactivities of these compounds in steam reforming decrease in the following trend: n-hexane > cyclohexane > I benzene > toluene > m-xylene >1-propanol > m-cresol > acetic acid. For the C6 hydrocarbons, benzene showed a lower reactivity than n-hexane and cyclohexane, due to the stable benzene ring. The reactivities of aromatic hydrocarbons decrease with the addition of methyl groups to the benzene ring due to electronic and steric effects. m-Cresol showed a lower reactivity than benzene, toluene, and m-xylene, suggesting that the incorporation of a hydroxyl group to the benzene ring hindered the steam reforming reaction. Besides the steam reforming reactions, the side reactions such as hydrogenolysis, demethylation, decomposition, and methanation of CO and CO2 also occurred. A benzene ring can be formed by the dehydroaromatization of n-hexane or cyclohexane, while the reverse reaction cannot occur due to the thermodynamic limit. The largely containing acetic acid in bio-oil needs a higher reforming temperature than the other compounds and is easy to be thermally decomposed into coke at low temperatures, which increases the difficulty of bio-oil steam reforming.

Effect of TiO2 Coating on Morphology of Active Phase on Sulfided CoMo/Al2O3 Hydrotreating CatalystsThanh Tung Nguyen; Imai, Kazunari; Pu, Jianglong; Qiang, Eika W.
ENERGY & FUELS
AMER CHEMICAL SOC
A series of CoMo catalysts supported on various Al2O3 supports added with TiO2 were prepared to investigate the addition effect of TiO2 on formation of an active phase on sulfided CoMo/Al2O3 catalyst. The catalytic activity tests were carried out with hydrodesulfurization (HDS) of 4,6-dimethyldibenzothiophene, hydrodenitrogenation (HDN) of acridine, and hydrodearomatization (HDA) of o-xylene, 1-methylnaphthalene (1-MN), and phenanthrene. A 20 wt % TiO2 added CoMoAlTi2O catalyst showed the lowest hydrogenation activity in HDA of 1-MN and phenanthrene and highest HDS and HDN activities. The property of a support and/or the interaction between active metal and the support significantly affect the formation of active sites for HDS and HDA. The active sites for HDS on sulfided CoMo catalysts were different from those for HDA and/or hydrogenation. The addition of TiO2 enhanced the reduction, the formation, and stacking number of CoMoS active slabs. The finding that desulfurization via the hydrogenation pathway (HYDS) activity increased while the HDA activity slightly decreased over TiO2 coated catalysts reveals that the increased amounts of formed CoMoS overcome the increase of the stacking number of CoMoS active slabs.

Hydrodesulfurization, Hydrodenitrogenation and Hydrodearomatization over CoMo/SAPO-11-Al2O3 CatalystsThanh Tung Nguyen; Shnzaki, Akira; Qian, Eika W.
JOURNAL OF THE JAPAN PETROLEUM INSTITUTE

Several SAPO-11-Al2O3 supports with different amounts of SAPO-11 were used to prepare a series of CoMo/SAPO-11-Al2O3 catalysts by the impregnation method with or without addition of citric acid. Hydrodesulfurization (HDS) of 4,6-dimethyldibenzothiophene, hydrodenitrogenation (HDN) of acridine, and hydrodearomatization (HDA) of o-xylene, 1-methylnaphthalene and phenanthrene were carried out to evaluate the catalytic activity of the catalysts. The catalysts were characterized by BET, XRF, NH3-TPD, XPS and TEM. The acidity of the supports strongly affected the active slabs structure and activity of the catalysts. 20 wt% SAPO-11 added catalyst showed lower HDA, HDS and HDN activities compared to CoMo/Al2O3 catalyst. The length and stacking number of CoMoS active slabs on the former increased because of decreased dispersion of Mo species due to the reduction in number of strong acid sites on the support surface in the presence of SAPO-11. Addition of citric acid during active metal impregnation decreased HDA activity but increased HDS and HDN activities due to improvement of Mo species dispersion, resulting in formation of shorter length and higher stacking of CoMoS active slabs.

Effect of ceria addition on Ni-Ru/CeO2-Al2O3 catalysts in steam reforming of acetic acidPu, Jianglong; Ikegami, Fumiaki; Nishikado, Katsuki; Qian, Eika W.
INTERNATIONAL JOURNAL OF HYDROGEN ENERGY
PERGAMON-ELSEVIER SCIENCE LTD
Ni-Ru bimetallic catalysts with different amount of CeO2 loaded on the gamma-Al2O3 support were prepared. The properties of catalysts were characterized by means of N-2 adsorption desorption, XRD, H-2-TPR and XPS techniques. Catalytic activities for the steam reforming of acetic acid over these catalysts were investigated at the temperature range from 650 degrees C to 750 degrees C. The addition of Ceo(2) dramatically improved the activity and stability of the catalyst. Among these catalysts, the NiRu/10CeAl catalyst showed the highest catalytic activity as well as a good stability owing to the abundant Ce3+ on the surface of catalyst. The existence of Ce3+ promoted the formation of CO2 from CO because of the mobilizable oxygen, which was favorable for the formation of hydrogen. The coke amount and species deposited on the catalysts after the activity tests were analyzed by DTG. As expected, the NiRu/10CeAl catalyst showed the best resistance to carbon formation. The temperature stepwise steam decoking experiment of the spent catalysts was conducted to elucidate the relationship between the existence of Ce3+ and the decoking abilities of various catalysts. It was verified that the existence of Ce3+ significantly promoted the decoking abilities of the catalysts. (C) 2017 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.

One-pot production of 5-hydroxymethylfurfural from cellulose using solid acid catalystsShirai, Hisakazu; Ikeda, Saki; Qian, Eika W.
FUEL PROCESSING TECHNOLOGY
ELSEVIER SCIENCE BV
5-Hydroxymethylfurfural (HMF) is one of the most important intermediate platforms for production of both chemicals and liquid fuel derived from biomass. The one-pot production of HMF from cellulose was conducted in a batch reactor in the presence of various solid acid catalysts. The prepared catalysts were characterized by means of Brunauer-Emmett-Teller measurement and pyridine adsorption FT-IR to investigate their pore structure and acidic properties. The presence of gaseous hydrogen enhanced the formation of HMF by suppressing the formation of byproducts. Increasing the acid amount of the catalyst caused an increase in the conversion and selectivity for organic add and a decrease in the HMF selectivity. A Bronsted-type catalyst (Al-SBA-15) favored the formation of HMF. The reaction conditions of 220 degrees C, 5 min, and a hydrogen pressure of 1 MPa resulted in the highest yield of HMF, and selectivity of 26.9% was achieved when the Al-SBA-15 catalyst was used. Moreover, under the same conditions, cellulose extracted from eucalyptus, a practical biomass, was converted to HMF in a one-pot synthesis with a yield of 13.0 C-mol.%. (C) 2016 Elstvier B.V.

Effect of surface modification with silica on the structure and activity of Pt/ZSM-22@SiO2 catalysts in hydrodeoxygenation of methyl palmitateChen, Ning; Wang, Ningning; Ren, Yuxiong; Tominaga, Hiroyuki; Qian, Eika W.
JOURNAL OF CATALYSIS
ACADEMIC PRESS INC ELSEVIER SCIENCE
To obtain diesel fuels with high combustion properties from hydrotreatment of vegetable oils, inhibiting the formation of multibranched isomers (MuBI) is highly desirable. A core@shell structural ZSM-22@SiO2 zeolite was designed to passivate external acid sites and promote the formation of monobranched isomers (MoBI), which have much higher cetane numbers than MuBI (>85 vs. <60). A series of ZSM-22@SiO2 zeolites with different amounts of shell silica were synthesized through a facile crystal growth method. External acid sites could be successfully inactivated using the proposed method. Synthesized zeolites were used as supports for bifunctional catalysts in hydrodeoxygenation of methyl palmitate. The effects of the shell silica amount and SiO2/Al2O3 ratio of the core zeolite were investigated. The MoBI percentage in total isomers increased from 71% to 95% at a reaction temperature of 300 degrees C. However, deoxygenation activity and isomerization selectivity decreased gradually with increasing amount of shell silica. Fourier transform infrared spectroscopy of CO adsorption combined with transmission electron microscopy demonstrated that Pt particles exposed more Pt(100) facets than Pt(11 1) facets in silica-coated catalysts. This could be the most likely reason for the decreased deoxygenation activity. The decrease in the number of Bronsted acid sites could be responsible for the lowered isomerization selectivity. Catalytic performance could be enhanced by reducing the SiO2/Al2O3 ratio of core ZSM-22. Catalysts with lower SiO2/Al2O3 ratios favored smaller Pt particles and exposed more active Pt(111) corner sites. Additionally, acid sites played an important role in the adsorption of oxygenates.
