【摘要】 选用铁、钼、锌为活性组分,ZSM-5沸石为载体制备了直溜汽油催化改质催化剂。考察了分子筛的不同硅铝比、不同的活性组分、活性组分含量、活性组分引入方式及反应条件等因素对催化剂性能的影响。结果表明:以硅铝比为50的ZSM-5分子筛为载体,以Fe2O3为活性组分、ZnO为助剂所制备的催化剂在常压3、20℃的条件下对直溜汽油进行催化改质,能使产物辛烷值(RON)提高32个单位,且具有较好的活性、稳定性。更多还原

【Abstract】 We prepared the requalitive catalyst of direct distillation gasoline by using iron,molybdeum and zinc as the active components and ZSM-5 zeolite as the carrier.We explored some factors to catalyst performance,such as different ratio of silior and aluminium,different active components,and so on.The results showed that the catllyst prepared by using ZSM-5 zeolite of the ratio of silicor and aluminium is 50 as the carrier,Fe₂O₃ as the active component and ZnO as the assistant catalysed the direct distillation gasoline in the condition of normal pressure and 320℃.It advanced 32 units of octane value,and has good activity and stability.更多还原
