摘要
以磷酸氢二胺和钼酸铵为原料,经氢等离子体法还原制备出单金属MoP及双金属Ni-MoP催化剂。采用XRD和SEM对催化剂进行分析表征;并在固定床反应器内以模拟油为研究对象评价催化剂活性。结果表明,双金属Ni-MoP催化剂的活性高于单金属MoP催化剂,二苯并噻吩转化率达到26.21%,联苯选择性达35.61%,环己烷基苯选择性达19.96%。
MoP and Ni-MoP catalysts were prepared by hydrogen plasma reduction using hydrogen diamine phosphate and ammonium molybdate as raw material.The catalyst was characterized by XRD and SEM,and evaluated in a fixed-bed reactor with simulated oil used as research object.The results showed that the activity of modified Ni-MoP catalyst was higher than MoP catalyst.The conversion of dibenzothiophene was 26.21%,selectivity of biphenyl and cyclohexalkylbenzene were 35.61% and 19.96% reapectively.
