Process and installation for producing electric power

The present invention is related to a process and an installation for the production of electric power or the cogeneration of electric and thermal power, wherein a hydrocarbon fuel is enriched through an endothermic reforming reaction on a mixture of said fuel with steam or water. According to the invention, the heat for the reforming reaction is supplied by the combustion of a material, preferably biomass, different from said hydrocarbon fuel. The invention is also characterized by the process integration of this reforming reaction in a gas turbine installation, wherein at least a part of the exhaust gases of the gas turbine are used as comburant air for the combustion of said material.
