NOVELTY - The process comprises gasifying a hydrocarbonized charge for producing a syngas, converting carbon monoxide contained in the syngas into hydrogen and carbon dioxide in the presence of water with a catalyst for producing a gas enriched of hydrogen and comprising carbon dioxide and hydrogen sulfide, contacting the gas enriched of hydrogen with a solvent for producing hydrogen flow impoverished of carbon dioxide and hydrogen sulfide, activating a turbine by a gas obtained by combustion of hydrogen flow, and regenerating the solvent for producing a flow rich in carbon dioxide.    USE - The process is useful for production of electricity with integrated gasification combined cycle by capturing and storing carbon and sulfur.    ADVANTAGE - The process is capable of economically and safely producing electricity with integrated gasification combined cycle by efficiently and simultaneously capturing and storing the carbon and sulfur in single step without producing any environmental pollution.    DETAILED DESCRIPTION - The process comprises gasifying a hydrocarbonized charge for producing a syngas, converting carbon monoxide contained in the syngas into hydrogen and carbon dioxide in the presence of water with a catalyst for producing a gas enriched of hydrogen and comprising carbon dioxide and hydrogen sulfide, contacting the gas enriched of hydrogen with a solvent for producing hydrogen flow impoverished of carbon dioxide and hydrogen sulfide, activating a turbine by a gas obtained by combustion of hydrogen flow, regenerating the solvent for producing a flow rich in carbon dioxide and comprising hydrogen sulfide, and compressing and injecting the flow rich in carbon dioxide and hydrogen sulfide in an underground reservoir. The turbine drives an alternator for producing electricity. The syngas mixed with water vapor is introduced in a first reactor and then in a second reactor, where the reactor comprises the catalyst. The first and second reactors are operated at a pressure of 25-30 bars and a temperature of 400-500 degrees C and 300-400 degrees C respectively. The syngas is produced by partial oxidation of the hydrocarbonized charge at a pressure of 25-60 bars and a temperature of 1200-1800 degrees C. The solvent comprises amine, alcohol and water. The water is vaporized by exchange of heat with an exhaust gas obtained from gas turbine. The vapor is expanded in the turbine to produce electricity. The hydrocarbonized charge is composed of pulverized carbon or petroleum residues. The compression or injection of carbon dioxide rich flow is performed for separating carbon dioxide from the underground reservoir or for increasing the reflow of hydrocarbons contained in the underground reservoir.
