PROCESS FOR THE ALKYLATION OF BENZENE-RICH REFORMATE USING MCM-49

摘要

The present invention relates to a process for alkylating a reformate feedstream containing benzene, toluene, xylenes, and ethylbenzene, said process comprising: 1) contacting said reformate feedstream with a hydrocarbon stream comprising C2-C5 olefins in the presence of a catalyst comprising an active form of synthetic porous crystalline MCM-49 under benzene alkylation conditions whereby an effluent stream is produced having a benzene content at least 50 wt.% less than that of said feedstream, an octane rating no less than that of said feedstream, and a total liquid product greater than that of said feedstream; and 2) collecting the gasoline boiling range fraction of said effluent stream.
