<p>The invention relates to a process for producing hydrogen and generating power comprising the following steps: (a) subjecting a gaseous hydrocarbon feedstock to an endothermic steam reforming reaction by contacting the hydrocarbon feedstock, in a steam reforming reaction zone, in the presence of steam, with a steam reforming catalyst under steam reforming conditions 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 compressor is drivingly coupled to the expansion turbine, wherein the oxidant is compressed in the in the compressor to obtain compressed oxidant and the fuel is combusted with the compressed oxidant in the combustion chamber to obtain a stream of combusted gas; (d) feeding at least part of the stream of combusted gas to the expansion turbine to generate power and to obtain a turbine flue gas; and (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.</p> |
