SUMMARY OF THE INVENTION The present invention is a method for alkylating a reformate feedstream containing benzene, toluene, xylene and ethylbenzene, comprising: 1) an active synthetic porous crystalline MCM-49. Contacting the reformate feed stream with a hydrocarbon stream comprising C 2 -C 5 olefins in the presence of a catalyst at benzene alkylation conditions so that the benzene content is at least 50% of the value in the feed stream. %, Wherein the octane number is not less than the value in the feed stream and the total liquid matter produces an effluent stream greater than the feed stream; and 2) recovering the gasoline boiling range fraction of the effluent stream.
