通过浸渍法制备了Ni-HZSM-5催化剂。利用XRD、SEM、N₂物理吸附、NH₃-TPD和Py-IR对催化剂进行表征，分别用丙烯、丁烯、2种比例丙烯丁烯的混烯、C₃~C₇多种混合烯烃等原料考察了催化剂烯烃齐聚反应的性能。结果表明，NiSO₄处理可以增加催化剂的酸度和介孔体积，其中Lewis和Brønsted酸性位点的数量和强度明显增加。Ni-HZSM-5分子筛催化剂在多种烯烃原料下均表现出优异的催化性能。不同烯烃原料下的齐聚反应转化率均在75%以上，选择性均在80%以上，产物碳数分布主要集中在C₆~C₁₆之间。

Ni-HZSM-5 catalyst is prepared through impregnation method.XRD,SEM,N₂ physical adsorption,NH₃-TPD and Py-IR are used to characterize the prepared catalyst.The performance of the catalyst is evaluated in oligomerizations of propylene,butylene,mixtures of propylene and butylene,and C₃-C₇ mixed olefins,respectively.The results show that the acidity and mesopore volume of the catalyst can be increased by adding NiSO₄,in which the number and strength of Lewis and Brønsted acid sites in the catalyst go up significantly.Ni-HZSM-5 molecular sieve catalyst exhibits excellent catalytic performance against various olefin raw materials.The conversion rates of the oligomerization reaction under different olefin feedstocks all exceed 75%,the selectivity is above 80% and the carbon number of the products distributes mainly between C₆-C₁₆.
