| 英文摘要 | Ammonium thiosulfate ((nh4)(2)s2o3) was used as an ex situ sulfiding agent to pretreat mo/al2o3 catalyst through impregnation. after h-2 activation, mo/al2o3 presulfided with (nh4)(2)s2o3 exhibits much higher catalytic activity in thiophene hydrodesulfurization (hds) than mo/al2o3 in situ sulfided by dimethyl disulfide. through (nh4)(2)s2o3 presulficlation, al2o3 support is modified by sulfate groups, leading to a decrease of interaction between mo and support; this promotes the formation of multi-layer type 11 mos2 that contributes to the high hds activity of the ex situ presulfided mo/al2o3 catalyst.
