A method for producing fuel comprised of gasoline rich in methanol and methyl ethers derived from coal, which process comprises gasifying the coal to produce carbon monoxide and hydrogen, steam shifting the gasification product to produce additional hydrogen, cleaning up the shifted product, catalytically converting the cleaned shifted gas to a mixture of alcohols, separating a methanol fraction from the mixture of alcohols, dehydrating the remaining alcohols to olefins, etherifying the olefin mixture with a portion of the removed methanol fraction, and blending into gasoline the resulting ether mixture and a second portion of the removed methanol fraction. |
