Název v původním jazyce
Support Effect in Hydrodesulfurization over Ruthenium Sulfide
Popis výsledku v původním jazyce
The hydrodesulfurization of thiophene over ruthenium sulfide on Al2O3, MgO, SiO2, TiO2, ZrO2 or active carbon was studied. The catalysts (1, 3 and 6 wt.% Ru) were prepared by impregnation with aqueous RuCl3. The only exception was the Ru/MgO catalyst which was prepared by impregnation with methanolic solution of Ru acetylacetonate. The catalysts were sulfided either in a 10%H2S/H2 or 20%H2S/N2 mixture at 400 oC. Their activity was tested at 400, 370 and 340 oC. The latter catalysts were mostly more active than the former. The difference increased with the loading and depended on support, the highest being with TiO2 and ZrO2 and the lowest with alumina and active carbon. The Ru sulfide catalysts were more active than the Mo/Al2O3 catalyst with corresponding loading. The order of activity was independent of activation method and increased in the order Ru/MgO, Ru/Al2O3,Ru/SiO2,Ru/ZrO2,Ru/TiO2,Ru/C.
