METHOD OF PRODUCING HYDROGEN WITH COMPLETE ENTRAPMENT OF CO AND RECYCLING OF UNREACTED METHANE Russian patent published in 2014 - IPC C01B3/32 C01B3/52 C01B3/56 B01D53/62 

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry. The method of producing hydrogen involves producing synthesis gas in an apparatus for steam reforming a hydrocarbon charge, steam conversion of the obtained synthesis gas to obtain a stream of hydrogen containing methane and carbon dioxide, trapping carbon dioxide present in the stream, trapping and returning methane, CO and CO₂ present in the stream of hydrogen to steam reforming.

EFFECT: invention increases purity of hydrogen and enables to use impurities during steam reforming.
