A method for improving the efficiency of a gasification combined cycle system for the coproduction of electric power and one or more chemical or liquid fuel products from a synthesis gas feed containing hydrogen and carbon monoxide. Waste heat is recovered from the chemical reaction system in the form of heated water which is used to heat and humidify one or more gas streams introduced into the combustor of the combined cycle system gas turbine. Waste refrigeration recovered from the synthesis gas purification system optionally is used to cool the air inlet to the gas turbine compressor.
