Abstract
A process for generating electrical power in a gas turbine cycle including an air compression stage, first and second gas combustion stages, and a series of first and second gas expansion stages. Mechanical power is provided for the generation of electrical power in a rotating power generator. The first combustion stage is operated on hydrogen-depleted fuel gas at high pressure using air from the air compression stage. The hydrogen-depleted fuel gas is obtained by endothermic catalytic steam reforming of a hydrocarbon feed gas. Heat for the endothermic steam reforming is supplied by indirect heat exchange with heat from hot exhaust gas from the second expansion stage. The second combustion stage is operated at lower pressure than the first combustion stage on exhaust gas from the first expansion stage and the hydrogen-enriched gas separated form the hydrogen depleted gas. The hydrogen-enriched gas is separated from the hydrogen-depleted fuel gas during the catalytic steam reforming of the feed gas.
