Patent ID: 7525002

Claim:
A method for producing a gasoline boiling range product from a mixed light olefinic feed stream comprising light olefins from ethylene up to butene and a liquid aromatic feed stream including single ring aromatic compounds, which process comprises: splitting the mixed light olefinic stream to form two mixed light olefinic streams, passing one of the two mixed light olefinic feed streams to a fixed bed of an olefin condensation catalyst comprising as the active catalytic component, an MWW zeolitic material to form a polymeric gasoline boiling range product by polymerization of the olefins in the stream; extracting olefins from the other of the two mixed light Fight olefinic feed streams by passing the olefinic feed stream in contact with the aromatic feed stream at a temperature to dissolve olefins in the liquid aromatic feed stream, passing the aromatic stream containing the extracted olefins to an alkylation step in which the aromatics are alkylated with the extracted olefins in the liquid phase over a fixed bed of a solid molecular sieve alkylation catalyst, to Form a gasoline boiling range product containing akylaromatics, combining the polymeric gasoline boiling range product and the gasoline boiling range product containing akylaromatics to form a gasoline boiling range product.
