Device for producing hydrogen has conversion stages and fine purification stage formed as hollow bodies having an annular chamber for receiving corresponding catalysts

摘要

Hydrogen production device comprises heated steam reforming stage with reforming catalyst to convert gaseous hydrocarbons and water into hydrogen, carbon monoxide and further reformer products, conversion stages to catalytically convert hydrogen, carbon monoxide and steam mixture leaving reforming stage, and fine purification stage to catalytically reduce residual carbon monoxide in conversion products. Device for producing hydrogen comprises heated steam reforming stage (1) with reforming catalyst to convert gaseous or vaporizable hydrocarbons and water into hydrogen, carbon monoxide and further reformer products, conversion stages (2a, 2b) connected to reforming stage to catalytically convert mixture of hydrogen, carbon monoxide and excess steam leaving reforming stage, and fine purification stage (3) connected to conversion stages to catalytically reduce residual carbon monoxide content of conversion products. Conversion stages and purification stage are each formed as hollow bodies having annular chamber for receiving corresponding catalysts.
