They were characterized by N2 and H2 sorption, TEM, TPR and by activity in HDS of thiophene and HDN of pyridine. The addition of Pt to sulfided Mo/MSA led to synergy in HDS and HDN with optimal Pt content close to 0.5 %. Generally, the Pt-Mo/MSA catalysts showed lower HDS and much higher HDN activities as compared to CoMo and NiMo/Al2O3.
