    • This invention provides a method of producing an aromatics alkylation catalyst comprising the steps of:(a) synthesizing a layered oxide material MCM-56 in the presence of alkali and/or alkaline earth metal cations;(b) prior to any calcination of the MCM-56, subjecting the MCM-56 produced in step (a) to ammonium ion exchange so as to at least partially replace the alkaline or alkaline earth metal cations associated with the MCM-56 with ammonium ions; then(c) heating the ammonium-exchanged MCM-56 to decompose the ammonium cations and convert the MCM-56 into the hydrogen form; and(d) after step (b), forming the MCM-56 into catalyst particles.The resultant catalyst exhibits enhanced activity in the alkylation of benzene with ethylene and propylene.
    • 本发明提供一种生产芳烃烷基化催化剂的方法,包括以下步骤:(a)在碱金属和/或碱土金属阳离子存在下合成层状氧化物材料MCM-56; (b)在MCM-56的任何煅烧之前,使步骤(a)中产生的MCM-56进行铵离子交换,以便至少部分地用铵与铵相关的碱金属或碱土金属阳离子 离子 然后(c)加热铵交换的MCM-56以分解铵阳离子并将MCM-56转化为氢形式; 和(d)步骤(b)之后,将MCM-56形成催化剂颗粒。 所得催化剂在用乙烯和丙烯烷基化苯中表现出增强的活性。
