| 摘 要： | 采用Ce和La对HZSM-5分子筛进行改性，考察在常压连续固定床反应器上混合C4烃催化裂解制低碳烯烃反应的催化性能，并对催化剂进行了S—BET、XRD表征。本文详细考察了反应温度、硅铝比及催化剂稳定性等各种因素对催化性能的影响。结果表明，改性后催化剂的催化裂解性能明显优于未改性的催化剂，其中以Ce改性催化效果较好，在480℃时反应较适宜，丙烯在反应后的气体中体积含量达到29．89／5。

| Abstract: | HZSM-5 zeolite modified by Ce and La was studied on performance of production of propylene and ethylene from C4 olefins by catalytic cracking in the fixed-bed reactor at atmospheric pressure, and catalyst was characterized by the S-BET and XRD. In this paper, a detailed study was done about effects of the reaction temperature, Si-Al ratio and the stability of catalyst and so on. The results showed that properties of the modified catalytic cracking catalysts are better than non-modified catalyst,and the cata... |
