ABSTRACT:
An apparatus is provided which is capable of removing impurities from an impurity-containing hydrogen gas without generating methane. A bed of particulate nickel in an amount of at least 5% by weight as elemental nickel at a temperature of from 0.degree. C. to 50.degree. C. removes all impurities except nitrogen. Then a bed of getter material, a zirconium, vanadium and iron alloy at a temperature of from 200.degree. C. to 800.degree. C. removes the nitrogen impurity thus producing purified hydrogen with an impurity content of less than 20 ppb.
