PROCESS AND APPARATUS FOR PRODUCTION OF HYDROGEN BY GASIFICATION OF COMBUSTIBLE MATERIAL AND METHOD FOR ELECTRIC POWER GENERATION USING FUEL CELL AND ELECTRIC POWER GENERATION SYSTEM USING FUEL CELL

摘要

The present invention relates to a hydrogen production method comprising a gasification step (1) for gasifying combustibles (a) and a gas processing step for refining a produced gas (b) to produce hydrogen. The gas processing step comprises a methanation step (5) for reacting carbon dioxide and carbon monoxide in the produced gas (b) obtained in the gasification step (1) with hydrogen to convert carbon dioxide and carbon monoxide into methane, and a hydrogen purifying step (6) for separating methane, nitrogen and argon in the gas after the methanation and purifying hydrogen gas.
