以具有中、大双孔结构的γ-Al2O3为载体制备了固载化AlCl3催化剂,并在悬浮床反应器中考察了其苯与1-C1=2烷基化反应活性。结果表明,该催化剂具有较高的转化率、选择性和催化稳定性。在1000小时连续反应过程中,烯烃转化率高于94%,单烷基苯选择性达到92%,其中2-苯基异构体选择性为42%。 The immobilized AlCl3 catalyst was prepared on the basis of γ-Al2O3 with double mesopore structure. The alkylation reaction of benzene and 1-C1 = 2 was investigated in a suspension-bed reactor. The results show that the catalyst has high conversion, selectivity and catalytic stability. During 1000 hours of continuous reaction, the olefin conversion was above 94%, the selectivity to monoalkylbenzenes was 92%, and the 2-phenyl isomer selectivity was 42%.
