摘　　要：筛选了可用于丙烯齐聚的阳离子交换树脂催化剂,研究了树脂性质与催化性能间的关系,并考察了自制LC001树脂催化丙烯齐聚的工艺条件。结果发现,采用大孔、高交换量的LC001树脂在150℃、4.0MPa、液时空速为1.5h-1条件下反应,丙烯单程转化率达到64.7%,C9和C12烯烃的选择性能达到58%。催化剂性能稳定,催化活性高,工艺流程简单,有很好的工业应用前景。A catalyst of cation exchange resin was selected to catalyze propylene oligomerization. The relationship between resin properties and catalytic activities were studied and the optimal reaction conditions of the typical resin LC001 were investigated. The propylene oligomerization was catalyzed by cation resin LC001 with macroporous and high exchange capacity. The once through conversion of propylene kept at about 64.7%, and the selectivity of nonene and dodecene in liquid products were about 58% under the optimized conditions of reaction temperature 150C, reaction pressure 4.0MPa and the LHSV 1.5hl. This catalyst displayed good stability, high activity and simple process. It showed a good prospect in industrial production.
