NOVELTY - The process comprises converting biomass or fossil fuels to a stream (20) of synthesis gases, analyzing characteristics of the stream of synthesis gases, supplementing the stream of synthesis gases with hydrogen gas from a source of hydrogen gas to produce a supplemented stream of synthesis gas with a regulated composition, generating synthesis gas stream from a carbonaceous feedstock, and reacting the supplemented synthesis gas stream with catalysts to convert carbon monoxide and hydrogen to reaction products to produce a stream of reaction products and unreacted synthesis gases.    USE - The process is useful for continuous production of electricity, heat and syngas derived products such as carbon monoxide, hydrogen and methane.    ADVANTAGE - The process ensures economical, safe, reliable and continuous production of electricity, heat and syngas derived products with improved mass and conversion energy efficiency and increased yield of liquid fuel products and without air pollutants and greenhouse gas emissions.    DETAILED DESCRIPTION - The process comprises converting biomass or fossil fuels to a stream (20) of synthesis gases, analyzing characteristics of the stream of synthesis gases, supplementing the stream of synthesis gases with hydrogen gas from a source of hydrogen gas to produce a supplemented stream of synthesis gas with a regulated composition, generating synthesis gas stream from a carbonaceous feedstock, reacting the supplemented synthesis gas stream with catalysts to convert carbon monoxide and hydrogen to reaction products to produce a stream of reaction products and unreacted synthesis gases, separating reaction products from the unreacted synthesis gases, and combusting the unreacted synthesis gases to produce electricity and heat. The process further comprises mixing the unreacted synthesis gases with the supplemented stream of synthesis gases, splitting the unreacted synthesis gases into two streams, recycling the mixed gas stream through the catalyst for a cycle, monitoring the characteristics of the pre- and post-catalyst gas stream, optimizing a ratio of recycle gas with synthesis gas to provide a synthesis gas stream that has highest reaction efficiency with the catalysts, concentrating the recycled unreacted gas stream before combustion, analyzing the monitored gas characteristics to establish optimum operating conditions using software models, controlling temperature, pressure, space velocity, chemical composition and recycle rates of the pre- and post catalyst synthesis gas streams, converting carbon dioxide gas in the synthesis gas stream to carbon monoxide gas, monitoring pressure, temperature, gas composition and flow rates of the synthesis gas flow and recycled synthesis gas flow with sensors, controlling the pressure, temperature, gas composition and flow rates of the synthesis gas flow and recycled synthesis gas flow and output of reaction products and electricity with a process controller, producing steam from excess heat from a gas combustion chamber, catalytic reactor and synthesis gas production to produce steam, generating electricity from the steam, gasifying the carbonaceous feedstock using the excess heat from combustion of the unreacted synthesis gases, providing chilled fluids for a condenser to separate reaction products from a post catalyst gas stream using the excess heat from combustion of the unreacted synthesis gases for an absorptive chiller, and controlling compressors (26), valves (44) and flow rates of gas with a process controller and sensors. The hydrogen source is generated by electrolysis of water with electricity generated by the system. An INDEPENDENT CLAIM is included for a catalytic reactor.
