DEVICE FOR THE GENERATION OF HYDROGEN

摘要

The invention relates to a device which is used to generate hydrogen, containing a. a heated steam reformation stage (1) with a reformer catalyst for the conversion of gaseous or vaporizable hydrocarbons and water into hydrogen, carbon monoxide and further reformation products, b. at least one stage which is arranged downstream from the steam reformation stage, for catalytically converting the mixture of hydrogen, carbon monoxide and excess steam emanating from the steam reformation stage (shift step) and c. a fine purification stage (3) which is arranged downstream from the conversion stage(s) for catalytic reduction of residual carbon monoxide content in conversion products by selective methanization. The invention is characterized in that the conversion stage (2) and the fine purification stage (3) are each embodied as a hollow body (exothermal catalyst stage).
