Abstract
In the conversion of coal to gaseous and liquid products, the heat value of the coal is more completely retained by the products through the selective high efficiency conversion of coal to a low ratio syngas utilizing a portion of the Fischer-Tropsch generated heat recovered as steam, conversion of the low ratio syngas with a water gas shift F-T catalyst to a product comprising C.sub.1 to C.sub.50 hydrocarbons and oxygenates, converting the F-T product to premium gas and increased liquid fuels comprising gasoline and distillate with a special zeolite catalyst and recovering the SNG and LPG products of the selective steps to provide an improved product slate. A portion of the produced fuel gas is used in lieu of coal to provide some of the heat energy requirements of the combination process.
