Abstract

A process for the purification of contaminated hydrogen gas which involves, first, subjecting the hydrogen gas to a preliminary purification with a hydride-forming material which has a low hydrogen storage capacity to remove substantially all of the contaminants, followed by a primary purification of the hydrogen gas with a hydride-forming material which has a high hydrogen storage capacity, thereby extending the useful life of the hydride-forming material which has the high hydrogen storage capacity.
