摘　　要：为实现塑料循环经济,分别采用多产丙烯型催化剂CGP和催化裂解催化剂DMMC-2探究废塑料热解油的催化裂化反应规律、产物分布和汽油馏分组成。结果表明:废塑料热解油具有良好的催化裂化生产汽油和催化裂解生产化工原料的性能;以增产汽油为目标时,汽油产率达52.37%,液化气产率为19.01%,其中丙烯产率为7.82%;以生产化工原料为目标时,低碳烯烃及苯、甲苯和二甲苯(BTX)的总产率可达47.82%,其中,乙烯、丙烯和丁烯(三烯)产率为32.51%,丙烯产率为16.67%,BTX产率达15.31%并以二甲苯为主。研究结果可为开发废塑料热解油的高值化利用技术提供参考。In order to realize the circular economy of plastics,the catalytic cracking reaction rule,product distribution and composition characteristics of pyrolysis oil from waste plastics were explored by using the catalyst CGP and DMMC-2,respectively.The results showed that the pyrolysis oil of waste plastics had good performance in the production of gasoline or and the raw chemicals by catalytic cracking.When aiming at increasing gasoline production,the gasoline yield can reach 52.37%,and the liquefied gas yield is 19.01%,of which the propylene yield is 7.82%;when the production of raw chemicals is the goal,the total yield of low carbon olefins and benzene,toluene and xylene(BTX)can reach 47.82%,of which the ethylene,propylene and butane yield is 32.51%and the propylene yield is 16.67%,and the yield of BTX reaches 15.31%,in which xylene is the dominate.The research results can provide a guidance for the development of high-value utilization technology of waste plastic pyrolysis oil.
