| 摘 要： | 介绍了中国石油兰州石化公司7万t／a液相分子筛制乙苯装置的工业运行情况，分析了影响烷基化催化剂及烷基转移催化剂活性的因素。结果表明，反应系统水含量、苯／乙烯加料比（摩尔比）、原料苯中碱性氮化物的含量是影响烷基化催化剂活性的主要因素；烷基转移反应入口水含量及二乙苯中的二苯乙烷含量是影响烷基转移催化剂活性的主要因素；在生产过程中，应控制原料苯中的水质量分数小于300×10^-6、碱性氮化物质量分数不大于400×10^-6，烷基转移反应入口水质量分数不大于50μg／g，二乙苯中二苯乙烷的质量分数小于0．02％。

| Abstract: | The running situation of 70kt/a ethylbenzene unit based on liquid-phase molecular sieve in Lanzhou Petrochemical Company of PetroChina was introduced,the influence factors on activity of alkylation catalyst and transalkylation catalyst were anlysized,and the countermeasures were proposed too.The results showed that the water content in reaction system,molar ratio of benzene to ethylene,and basic nitride content in benzene were key factors that influenced the activity of alkylation catalyst.The water content... |
