摘要
以硅溶胶为硅源 ,合成MCM -4 1分子筛 ,并将CuCl2 单层负载于MCM -4 1分子筛上 ,然后再将AlCl3 负载于CuCl2 上 ,制得催化剂。考察不同负载方法和负载量对催化剂酸性的影响 ,并将该催化剂应用于异丁烷和丁烯的烷基化反应中 ,显示了较高的活性。高压气相和超临界条件下催化剂反应性能评价结果表明 。
Mesoporous molecular sieve MCM-41 was synthesized with silicon as the Si source by hydrothermal method.The catalyst was prepared by dispersing CuCl 2 and AlCl 3 on the MCM-41.The effect of dispersion methods and dispersion amount on the acidity of the catalyst was investigated.The catalyst A exhibits good performance in the alkylation of isobutane with butene.Under the supercritical reaction conditions,the lifetime of the catalyst can be prolonged greatly by alleviation of coking.
