FIELD: technological processes; power engineering.
SUBSTANCE: invention relates to a method for producing hydrogen and generating power. Method comprises the following steps: (a) subjecting raw gaseous hydrocarbons to an endothermic steam reforming reaction in a steam reforming reaction zone to obtain a gaseous mixture comprising hydrogen and carbon monoxide; (b) recovering hydrogen from the mixture; (c) feeding a fuel and an oxidant to a turbine comprising in series a compressor, a combustion chamber and an expansion turbine, wherein the fuel is burnt with the compressed oxidant in the combustion chamber to obtain a stream of flue gas; (d) feeding at least part of the stream of flue gas to the expansion turbine to generate power and to obtain a turbine flue gas; (e) providing heat for the endothermic reforming reaction by bringing a hot gas stream generated in step (c) and/or step (d) in heat exchange contact with the steam reforming reaction zone; and (f) liquefaction of the hydrogen recovered in step (b) by subjecting the hydrogen recovered to a liquefaction cycle comprising cooling and compressing the hydrogen.
EFFECT: technical result is to develop a method that allows for additional generation of energy for the same amount of fuel.
