a process for integration of a steam reforming unit and a cogeneration power plant in which said steam reforming unit comprises two communicating fluid beds ; the first fluid bed comprising a reformer containing catalyst and which is used to react steam and light hydrocarbons at conditions sufficient to produce a mixture comprising synthesis gas hydrogen , carbon monoxide , and carbon dioxide , the second fluid bed comprising a combustor - regenerator which receives spent catalyst from the first fluid bed and which provides heat to heat the catalyst and balance the reaction endotherm , by combusting fuel gas in direct contact with the catalyst producing hot flue gas ; said cogeneration power plant comprises a gas turbine equipped with an air compressor and a combustor ; said integration which comprises drawing off a portion of compressed air from the power plant gas turbine air compressor leaving remainder compressed air ; introducing the drawn off compressed air to the combustor - regenerator ; mixing the hot flue gas from the combustor - regenerator with the remainder of the compressed air to produce a recombined gas stream and feeding this recombined gas stream to the combustor of the cogeneration gas turbine power plant .
