The results showed that It was feasible to sulfurize hydrotreating catalyst by acidity gas. The bromine number was still less than 0.5gBr_2/100g when the concentration of CO_2 was up to 1.5 times concentration of H2S.
This paper studies the influence to the subtractive effect created by reaction temperature, binary acid dosage, solvent, samming time, and centrifugal separation condition while subtrated styrene-butadien-styrene hydrogenated catalyst by precipitation. The optimum reaction conditions are obtained: the temperature is between 65-75℃; the mol ratio between precipitating agent and metal is 2 : 1;
In the case of hydrotreatment of WMO, the liquids obtained over RM at both 400° and 425°C had larger amounts of low-boiling hydrocarbons than that of thermal or catalytic treatment with hydrotreating catalyst.
M?ssbauer emission and absorption studies on the reduction behaviour of supported Co, Co-Mo, Fe and Fe-Mo hydrotreating catalyst
Effect of vanadium over NiMo/sepiolite hydrotreating catalyst
An unsteady-state kinetic model of both benzene hydrogenation (HDA) and thiophene hydrogenolysis? (HDS) on a sulfide hydrotreating catalyst Ni-Mo/Al2O3 has been developed.
Influence of support on activity of diesel fuel hydrotreating catalyst
The results showed that the catalyst had higher catalytic performance than common hydrogenation catalysts.
The conversion of CNB could reach 99.9%, and the dechlorination of chloroaniline (CAN) was less than 1.9% when catalyzed by Pt-Sn-B/CNTs and more than 8.0% when catalyzed by common hydrogenation catalysts.
The Development and Use of New Hydrogenation Catalysts1
Polynuclear palladium complexes with phosphide and phosphinidene ligands are obtained, and their role in the formation of hydrogenation catalysts is found.
