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.
