Catalytic cracking of bitumen with steam was examined. The heavy oil fraction of bitumen reacted with active oxygen species generated from steam with the iron oxide catalyst, producing significant amo...
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 ...
To suppress total oxidation and increase the CO selectivity of high-pressure oxidative reforming of methane, preparation parameters of K−Ni/α-Al2O3 catalyst were optimized. The target preparatio...
Dehydrogenation of ethylbenzene was evaluated with Fe–K and Fe–Ce–K mixed oxide catalysts to examine the addition effect of Ce. Fe–Ce mixed oxide was prepared by co-precipitation of Fe and Ce nitrate ...
A nascent surface has high activity to catalyze the decomposition of lubricants under boundary lubrication conditions. The effects of sulfur-containing, nitrogen-containing, phosphorus-containing addi...
The dissolution amount was measured by the method of differential heat of adsorption for Akabira coal and among three types of gases,CO2 exhibited the substantial dissolution. Therefore, CO2 storage ...
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...
Ru/Al2O3 catalyst was investigated by using Mn addition for Fischer-Tropsch synthesis under pressurized conditions. On the basis of catalyst activity, selectivity and deactivation, small amount of Mn...
A series of bimetallic Pd-Pt (mole ratio Pd:Pt=4:1) catalysts supported on ultrastable Y (USY) zeolites and delaminated USY zeolites were prepared and characterized by XRD, 27Al MAS NMR and CO adsorp...
Resid hydrodesulfurization catalyst was regenerated after commercial operation and the effect of vanadium accumulation during resid hydrotreating reaction on the following catalyst regeneration was i...
The effect of sulfidation on 129Xe NMR spectra of Co-Mo/Al2O3 hydrodesulfurization catalysts was investigated. Before sulfidation, catalysts containing cobalt such as Co/Al2O3 and Co-Mo/Al2O3 showed ...
The present study investigated the structure of Co species formed during the preparation of Co/SiO2 Fischer-Tropsch synthesis (FTS) catalysts with an aqueous Co nitrate solution modified with chelati...
To clarify the effect of sulfur compound addition on catalytic activity and catalyst deactivation, hydrodesulfurization (HDS) of coker gas oil (CGO) was carried out over demetallation catalysts, meta...
ZSM-5 supported Mo catalysts for the dehydroaromatization reaction of methane were characterized by Mo K-edge EXAFS, NH3-TPD, and XPS techniques. Mo/ZSM-5 catalysts showed the maximum activity for be...
