摘要
对以Al2O3为载体的金属氧化物催化剂催化FCC汽油选择性加氢反应进行了研究。考察了单组分、双组分及三组分元素组合对催化剂选择性加氢脱双烯脱硫醇性能的影响。实验结果表明,双组分催化剂的选择加氢脱双烯脱硫醇的性能明显优于单组分催化剂;经过适当组合的三组分催化剂的选择加氢脱双烯脱硫醇的性能较好,尤其是TiNiMo/Al2O3催化剂的加氢性能最好,在高液态空速(9 h-1)下反应100 h,异戊二烯的转化率大于70%,乙醇硫的转化率为100%,总单烯饱和度为0;且该催化剂还表现出一定的双键异构活性。
Metallic oxide catalysts supported on Al2O3 were prepared and used in the selective hydrogenation of FCC light gasoline. The effects of different element associations on the catalytic performances of the selective hydrogenation catalysts in removing diolefins and mercaptans in the FCC light gasoline were investigated. The results showed that the catalytic performances of bi-component catalysts were better than those of mono-component catalysts and the hydrogenation performance of appropriately combined three component catalysts is the best, especially TiNiMo/Al2O3. Under the conditions of LHSV 9 h^-1 and reaction time 100 h, diolefin hydrogenation conversion and mercaptan removal rate can reach more than 70% and 100% respectively, the total mono-olefin saturation degree is 0, and the TiNiMo/Al2O3 catalyst has proper double-bond isomerization activity also.
