A power generating method that includes the steps of burning a reformed fuel in the presence of air in a combustor of a gas turbine to generate a hot exhaust gas is disclosed. The hot exhaust gas is then passed through a turbine section of the gas turbine to generate power and, thereafter, the hot exhaust gas is passed through a heat recovery system where the hot exhaust gas is successively cooled as it passes through a series of heat exchangers. Heat exchangers comprising the heat recovery system include combustion air pre-heater(s); a thermochemical recuperator (or reformer), wherein hot exhaust gas provides the endothermic heat of reaction necessary to reform a raw fuel/steam mixture to the combustible, reformed fuel that is eventually burned in the combustor; and one or more water/steam heaters which supply steam to a low-pressure, condensing steam turbine of a bottoming Rankine cycle to generate additional power. A cooled exhaust gas exits the heat recovery system and, optionally, may be sent to scrubbers and/or other unit operations for further processing, such as removal of harmful toxins, before being vented to the atmosphere.

[ What is claimed is:] [1.]1. A method of generating power, the method comprising the steps of:(a) burning a reformed fuel in the presence of compressed air in a combustor to produce an exhaust gas having an elevated temperature with respect to ambient temperature;(b) passing a portion of the exhaust gas produced in step (a) through a gas turbine to generate power;(c) reforming a mixture of steam and a raw, natural gas-derived, oxygenated fuel capable of being reformed at a temperature of about 300.degree. F. to about 932.degree. F., by passing the mixture through a catalytic reactor in indirect heat exchange relationship with the exhaust gas from an outlet of the gas turbine of step (b) to provide an amount of heat from said exhaust gas sufficient to reform the mixture to produce the reformed fuel burned in step (a); and, (d) passing at least a portion of the exhaust gas from the catalytic reactor through a heat exchanger of a Rankine cycle to generate power in the Rankine cycle,wherein the amount of power generated in the Rankine cycle, based on the overall power generated is less than about 30%.
