ABSTRACT:
An integrated process for the production of alkylate and etherate rich high octane gasoline streams comprising the etherification to produce MTBE and TAME in the presence of a high stoichiometric excess of methanol followed by the conversion of unreacted methanol in contact with zeolite-type catalyst in the presence of aromatics to produce alkylated aromatics in gasoline. The light paraffinic effluent from the methanol conversion zone is reacted in contact with zeolite catalyst under aromatization conditions to produce an aromatics feedstream for the methanol conversion reaction. A supplemental olefinic feedstream is provided to the methanol conversion zone after optionally serving as stripping medium for the separation of methanol and etherate-rich C.sub.5 + gasoline from the etherification reaction.
