DEVICE FOR PRODUCING HYDROGEN FROM CARBON SOURCE

摘要

PROBLEM TO BE SOLVED: To produce high purity gaseous hydrogen without needing a complicated process and to selectively separate the high purity gaseous hydrogen from the produced gas. SOLUTION: A hydrogen separating pipe 13 for separating and taking out hydrogen from the produced gas is provided inside a reactor 10 for producing the gas consisting essentially of hydrogen and carbon dioxide by reacting water in a sub-critical or super-critical state with the carbon source. The reactor has a gas take-out pipe 24 for taking out a gas except hydrogen. The gas except hydrogen is separated into a gas consisting essentially of carbon dioxide and water by a 1st gas-liquid separator 26 and the separated gas is separated into a gas consisting essentially of methane and carbon dioxide by a 2nd gas-liquid separator 28. The hydrogen separating pipe is constituted of a hydrogen permeable heat resistant porous pipe so as to carry a metal on the surface of the porous pipe.
