Hydrogenation of naphthalene in the presence of CO was examined as a step in the organic hydride method for utilizing low grade hydrogen. Development of CO-tolerant hydrogenation catalysts will allow ...
Waste cooking oil contaminated with fish oil has potential uses as a biodiesel fuel feedstock. The changes in properties of fish oil fatty acid methyl ester (FAME) caused by oxidation were first evalu...
The organic hydride method utilizes the reversible hydrogenation-dehydrogenation cycle of aromatic hydrocarbons for the storage and transportation of hydrogen. If low-grade hydrogen containing CO imp...
A series of bimetallic palladium-platinum (molar ratio Pd : Pt=4 : 1) catalysts supported on ytterbium (Yb)-modified ultrastable Y (USY) zeolite, Pd-Pt/Yb-USY, were prepared and characterized to inve...
The reaction pathway for hydrogenation of 2-butyne-1,4-diol involves parallel and consecutive isomerization as well as hydrogenation reactions forming other side products along with cis-2-butene-1,4-...
Newly developed CoMo titania catalysts for ultra-deep hydrodesulfurization (HDS) of diesel oil have higher activities for both HDS and hydrodenitrogenation (HDN), whereas the chemical hydrogen consum...
Effects of the carrier characteristics were studied on the catalytic properties of Pt-Pd-supported USY zeolites in the hydrogenation of tetralin and the hydrodesulfurization of 4,6-dimethyldibenzothio...
A hybrid catalyst consisting of a methanol synthesis catalyst and a methanol dehydration catalyst was used for the direct synthesis of dimethyl ether (DME) from CO2 and H2. Particle-shaped hybrid cat...
The present study investigated the effects of trans-1,2-cyclohexanediamine-N,N,N',N'-tetraacetic acid (CyDTA) addition on the 1-octene hydrogenation activity and surface structure of CoMo/Al2O3 catal...
Direct DME synthesis from CO2 and H2 was carried out using hybrid catalysts consisting of a methanol synthesis catalyst (CuO-ZnO-Al2O3-Ga2O3-MgO) and a methanol dehydration catalyst (γ-Al2O3 or ZrO2...
The present study investigated the effects of Co addition on the surface structure and activity of Mo/Al2O3 for the hydrogenation of C6-C10 olefins. CoMo/Al2O3 (Co/Mo atomic ratio: 0.56) had lower ac...
The present study investigated the effects of chelating agents on the aromatic hydrogenation activity and the surface fine structure of NiW/Al2O3 catalyst. NiW/Al2O3 catalyst was prepared from impreg...
The adsorption species on ZrO2 or Cr-ZrO2 catalyst in the hydrogenation of dimethyl benzenedicarboxylates as well as benzoic acid were characterized by diffuse reflectance FT-IR and CP/MAS 13C-NMR spe...
Dimethyl terephthalate was hydrogenated over ZrO2 catalyst in the vapor phase to form terephthalaldehydic acid methyl ester and terephthalaldehyde as the major products. The reactivity of the three r...
Charcoal-supported rhodium and ruthenium catalysts were active and selective for the hydrogenation of biphenyl to bicyclohexyl at low temperature (323 K) under supercritical carbon dioxide. The conve...
