Abstract
Utilizing air, rather than oxygen, to convert coal to synthesis gas containing very high proportions of inert nitrogen; subjecting this entire gas, possibly with intermediate cleanup, e.g., sulfur removal, to conversion over a special metal-zeolite catalyst to produce a product comprising C.sub.5 to C.sub.11 normally liquid hydrocarbons, a gas containing C.sub.1 to C.sub.4 hydrocarbons, carbon dioxide and large proportions of nitrogen, and an aqueous product comprising water; utilizing the gas product to run electric power generation equipment, such as a direct fired turbine, at base load levels; storing and accumulating the liquid product; and intermittently using the liquid product for electric power generation to meet higher than base loads, including peak load situations.
