Device for the generation of hydrogen

摘要

An apparatus for producing hydrogen, which comprises: a. a heated steam reforming stage ( 1 ) with a reforming catalyst to convert gaseous or vaporizable hydrocarbons and water into hydrogen, carbon monoxide and further reformer products; b. at least one stage downstream of the steam reforming stage for the catalytic conversion of the mixture of hydrogen, carbon monoxide and excess steam leaving the steam reforming stage (shift stage) ( 2 ); and c. a fine purification stage ( 3 ) downstream of the shift stage(s) for the catalytic lowering of the residual carbon monoxide content of the conversion products by selective methanization, is described. In the apparatus, the shift stage ( 2 ) and the fine purification stage ( 3 ) are configured as a unitary hollow body (exothermic catalyst stage).
