| 英文摘要 | two series of sulfided ni or co promoted mo/alumina catalysts, having different ni or co loadings, were characterized by their activities for the transformation of cyclopentanone into cyclopentanethiol (flow reactor, 220 degrees c, atmospheric pressure) and for the hydrodesulfurization of dibenzothiophene (flow reactor, 340 degrees c, 3 mpa hydrogen pressure). the addition of the promoter increased significantly the activity of the mo/alumina catalyst for both reactions, up to a maximum obtained with the catalysts having a (promoter)/(promoter+mo) molar ratio equal to 0.3-0.4. this increase in activity was due in part to an increase in the hydrogenating properties of the mo/alumina catalyst. however, an additional modification of the catalyst (basic and nucleophilic properties) must be considered to account for the spectacular effect of the promoter on the rate of the dibenzothiophene direct desulfurization reaction.
