<P>PROBLEM TO BE SOLVED: To simply regenerate an adsorption section and adequately reduce an amount of hydrogen to be disposed. <P>SOLUTION: A method for regenerating the adsorption device in a hydrogen production system comprises the steps of: moving a high-pressure hydrogen gas in a first adsorption column 40a to a second adsorption column 40b to equalize the pressure in the inside of the first adsorption column 40a to that of the second adsorption column 40b, when regenerating the first adsorption column 40a; releasing the gas remaining in the first adsorption column 40a to a disposing section; and using the high-pressure hydrogen gas which has been moved to the second adsorption column 40b as a product gas. The high-pressure hydrogen gas that has been moved to the second adsorption column 40b is used as the product gas, which accordingly reduces the amount of hydrogen gas to be wastefully disposed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
