摘　　要：对比分析了煤基石脑油裂解制丙烯与甲醇制烯烃工艺合成丙烯在不同聚合条件下的聚合行为,实验结果表明:随着静置时长增加,丙烯1聚合反应的活性逐渐降低,甚至出现不聚合的现象,而丙烯2聚合反应的活性无明显变化;使用同一催化剂催化丙烯聚合,丙烯1聚合反应的活性、聚合产物的熔融指数与等规度均低于丙烯2;使用不同催化剂催化丙烯聚合反应,丙烯1和丙烯2的变化趋势一致;在一定范围内增大三乙基铝用量可以明显提升丙烯聚合活性,而对聚合产物的熔融指数和等规度无明显影响。In this paper,the polymerization behavior of propylene synthesized from coal-based naphtha cracking to propylene and methanol to olefins under different polymerization conditions was compared and analyzed,the experimental results show that:With the increase of standing time,the activity of Propylene 1 polymerization reaction gradually decreased,and even non-polymerization appeared,however,there was no significant change in the activity of Propylene 2 polymerization;The same catalyst was used to catalyze the polymerization of propylene,and the activity of Propylene 1 polymerization reaction,melt index and isotactic index of polymerization products were lower than those of Propylene 2;Different catalysts were used to catalyze the propylene polymerization reaction,and the change trend of Propylene 1 and Propylene 2 was consistent;Increasing the dosage of triethyl aluminum within a certain range can significantly improve the polymerization activity of propylene,but has no significant effect on the melt index and isotactic index of the polymerization products.
