ABSTRACT:
Methanol or other alcohol is converted to high octane gasoline components by an integrated process wherein crude aqueous alcohol feedstock is extracted with a liquid extractant stream containing C.sub.4.sup.+ iso-olefin and reacted to form tertiary-alkyl ethers, such as MTBE. The aqueous raffinate is converted to predominantly gasoline range liquid hydrocarbons in a MTG catalytic reactor, with byproduct alkanes rich in propane and isobutane. Dehydrogenation of C.sub.3 -C.sub.5 alkanes from the MTG unit provides propene and isobutene reactants for subsequent etherification steps. Propene from the MTG dehydrogenation step is reacted with water to produce di-isopropyl ether, which may be blended with MTBE and C.sub.6.sup.+ MTG hydrocarbons to produce high octane gasoline. Isobutylene and isoamylenes from the MTG dehydrogenation step can be removed and recycled as a liquid extractant stream.
