ABSTRACT:
Aliphatic oxygenates are converted to high octane gasoline by an integrated process wherein three reaction zones are utilized. In a first reaction zone the oxygenates are directly converted to gasoline and an isobutane by-product. In a second reaction zone oxygenates are dehydrated to an intermediate product comprising C.sub.3 -C.sub.4 olefins, which are then further reacted with the isobutane by-product in a third reaction zone to yield a gasoline alkylate. Ethylene-containing vapors may be separated from the second reaction zone and recycled to the first reaction zone for further processing.
