desulfurization-hydrogenation
1.Similar inhibition occurred in the HDS reaction of DBT over CoMo/Al_2O_3, however, in the case of DMDBT, H_2S suppressed direct desulfurization route while promoted hydrogenation route.
2.Compared with MOP/Al_2O_3, MoP/MCM-41 shows higher HDS activity. The distribution of HDS products suggests that hydrodesulfurizations of DBT predominately takes the route of direct desulfurization over MoP/Al_2O_3 but that both hydrogenolysis and hydrogenation play important rule in the hydrodesulfurization of DBT catalyzed by MoP/MCM-41.MoP/MCM-41 prepared by different activation ways was valuated for DBT HDS.
