Abstract :
HDS activity of sulfided Mo (W) catalysts supported on carbon black composites (CBC) is affected by kind of functional groups present on the CBC surface. Oxidation of CBC with (NH4)2S2O8 produce functionalities with the highest acid strength and corresponding catalyst exhibits the highest HDS activity. Sulfided W/CBC is less active in thiophene HDS than corresponding Mo counterpart. The rate of thiophene HDS over Mo/“basic” CBC does not depend on the method of Mo deposition.
