摘要： 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.

摘要： This is a process for upgrading a petroleum naphtha fraction. The naphtha is subjected to reforming and the reformate is cascaded to a benzene and toluene synthesis zone over a benzene and toluene synthesis catalyst comprising a molecular sieve of low acid activity. The preferred molecular sieve is steamed ZSM-5. The benzene and toluene synthesis zone is operated under conditions compatible with the conditions of the reformer such as pressures of above about 50 psig (446 kPa) and temperatures above about 800.degree. F. (427.degree. C). In one aspect of the invention, the benzene and toluene synthesis catalyst includes a metal hydrogenation component such as cobalt, nickel, platinum or palladium. In one mode of operation, the benzene and toluene synthesis catalyst replaces at least a portion of the catalyst of the reformer. The process produces a product containing an increased proportion of benzene and toluene, and a reduced proportion of C8 aromatics, particularly ethylbenzenes, as compared to the reformate.
