Claim 12:
13. A system for producing an alkylaromatic compound, the catalyst system comprising:
(a) a first bed comprising an adsorbent for contacting a first feed comprising an alkylatable aromatic compound containing an impurity compound comprising at least one of the following elements: nitrogen, halogens, oxygen, sulfur, arsenic, selenium, tellurium, phosphorus, and Group 1 through Group 12 metals under conditions effective to reduce an amount of impurity compound in the first feed and produce a purified first feed, wherein the adsorbent comprises a metal-organic framework material; and
(b) a second bed downstream of, and connected to, the first bed for contacting the purified first feed with a second feed comprising an alkylating agent under alkylation conditions effective to convert at least part of the alkylatable aromatic compound in the purified first feed to the alkylaromatic compound and produce an alkylation effluent, wherein the second bed comprises an alkylation catalyst composition comprising a zeolite selected from the group consisting of beta, faujasite, mordenite and a zeolite of the MCM-22 family.
