| 摘 要： | 对丙烯和苯液相烷基化反应中的几种分子筛的性能进行了比较研究。结果表明,MCM-56分子筛催化剂烷基化反应稳定性及产物选择性明显优于Y、β分子筛催化剂。MCM-56分子筛催化剂更能适应低温反应和低苯烃比反应,推荐工艺条件为:温度130～145℃、压力2 5MPa、n(苯)/n(烃)=2～3、丙烯空速0 8～1 0h-1。

| Abstract: | Different molecular sieves for liquid phase alkylation of benzene with propylene were compared. Results show that the new synthetic porous crystalline material MCM-56 molecular sieve exhibits excellent reaction stability and product selectivity in comparison with the traditional Y and β molecular sieves.The MCM-56 molecular sieve was more adaptable to lower temperature reaction and lower mole ratio of benzene to propylene. The recommended reaction conditions were:reaction temperature,130～145 ℃;reaction pressure, 2 5 MPa; mole ratio of benzene to propylene,2～3;and space velocity of propylene,0 8～1 0 h -1 |
