<p>An integrated process for the production of alkylate and etherate rich high octane gasoline streams (113, 121 and 122) is provided which process comprises etherification (reactor A) to produce MTBE and TAME (113) in the presence of a high stoichiometric excess of methanol (110) followed by the conversion of unreacted methanol (114) in contact with zeolite type catalysts in the presence of aromatics (119) produce alkylated aromatics in gasoline. The light paraffinic effluent (120) from the methanol conversion zone (reactor B) is reacted in contact with a zeolite catalyst under aromatization conditions (reactor C) to produce an aromatics feedstream (124) for the methanol conversion reaction (reactor B). A supplemental olefinic feedstream (128) is provided to the methanol conversion zone (reactor B) after optionally serving as stripping medium for the separation (reactor E) of methanol (114) and etherate-rich C5 + gasoline (113) from the etherification reaction (reactor A).</p> |
