University of Tehran Journal of Sciences, Islamic Republic of Iran 1016-1104 13 3 2002 09 01 SYNERGIC PROMOTION OF CATALYST BY GROUP VIII B ELEMENTS - 31718 EN Journal Article 1970 01 01 Group VIII B metal oxides supported on gamma-alumina were investigated as catalysts and promoters of MoO3 hydrodesulfurization catalysis. Superior promotion was observed in PbO promoted catalyst compared to that of CoO, the typically accepted promoter. Other metal oxides, SnO and Ho2O3 exhibited reasonable hydrodesulfurization catalysis promotion but lower than for CoO promoted catalyst. https://jsciences.ut.ac.ir/article_31718_c0cce8b167fa45846abc9f34a3925781.pdf
