ABSTRACT:
An integrated process for converting coal to high octane gasoline by gasifying the coal in such manner as to form a gas comprising carbon oxides, hydrogen and methane; contacting this gas in one or a series of steps with one or a series of catalysts, respectively comprising a special high silica to alumina ratio zeolite; converting the carbon oxides and hydrogen by such contact to a product comprising water, high octane aromatic gasoline and light hydrocarbon gases; alkylating the C.sub.3 and C.sub.4 olefins with the isobutane in the light gases to produce alkylate gasoline; admixing the aromatic and alkylate gasolines; and subjecting the C.sub.2.sup.- portion of the product to catalytic methanation via a nickel catalyst to produce synthetic natural gas.
