| 英文摘要 | To improve the hydrodesulfurization activity while to minimize the hydrogen consumption from the hydrogenation of olefins is of importance for the deep desulfurization of gasoline. herein, a series of co/mos2 +/- x catalysts were prepared by impregnating co-promoter to mos2 +/- x (x < 0.06) with controllably varied s/mo atomic ratio. the s/mo atomic ratio of mos2 +/- x in co/mos2 +/- x catalysts influences the catalytic performance of co/mos2 +/- x in simultaneously thiophene hydrodesulfurization (hds) and cyclohexene hydrogenation (hyd) reactions. with decreasing the s/mo atomic ratio in co/mos2 +/- x, the hds selectivity factor (k(hds)/k(hyd)) increases to two times (from 37 to 89), although the catalytic activities of hds and hyd decrease due to the low content of comos phase. the higher selectivity of co/mos2 +/- x with lower s/mo atomic ratio could be well explained by larger size of sulfide crystallites exposed lower corner sites. therefore, a high hds selectivity catalyst could be developed by properly controlling the crystal size of sulfide crystallites.
