英文摘要 | hydrodesulfurization (hds) of dibenzothiophene (dbt) over ptmo/al2o3 was studied in the presence of h2s. pt was found to be an effective promoter for this reaction and the pt-containing catalyst was sulfur tolerance. data of the h-2-d-2 exchange revealed that both the amount of retained hydrogen and the initial rate of h-d exchange on the sulfided catalyst were increased by the introduction of a slight amount of pt into the catalyst, and corresponded very well to the catalytic activities for hds. the reduction and sulfidation of mo sites was also facilitated very much by pt, which was found by the results of the pulse reduction and sulfidation technique. it is proposed that, during the pretreatment of ptmo/al2o3, h-2 is first dissociated into hydrogen atoms on pt sites, which then spillover onto mo sites, providing a large amount of coordinately unsaturated mo sites for the hds reaction, and resulting in the higher hds activity than the unpromoted one. |
