Abstract
A method is provided for maximizing the production of electrical energy from coal by improving the thermal efficiency of gasifiers used in integrated coal gasification combined cycle gas turbine (IGCC) systems. Coal is reacted in a gasifier to produce a product fuel gas containing carbon monoxide from combustion of the carbon of the feed coal, plus additional carbon monoxide from the reduction of carbon dioxide, wherein the reaction of carbon monoxide with water is avoided to conserve the work potential of the product fuel gas which will increase the efficiency of conventional gas turbine systems and high temperature fuel cells. Combustion of the product fuel gas with oxygen produces carbon dioxide which is readily recovered from the exhaust by removal of water, such as from combustion of hydrogen in the coal, and molecular hydrogen from the coal may recovered by permeation through a hydrogen permeable membrane.
