Beschreibung
Zusammenfassung:	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 COpresent in the stream of hydrogen to steam reforming.EFFECT: invention increases purity of hydrogen and enables to use impurities during steam reforming.15 cl, 12 dwg, 2 ex Изобретение относится к области химии. Способ получения водорода включает получение синтез-газа в установке парового риформинга углеводородной загрузки, паровую конверсию полученного синтез-газа с получением потока водорода, содержащего метан и диоксид углерода, улавливание диоксида углерода, присутствующего в потоке, улавливание и возврат на паровой риформинг метана, CO и CO, присутствующих в потоке водорода. Изобретение позволяет повысить чистоту водорода и использовать примеси в процессе парового риформинга. 14 з.п. ф-лы, 12 ил., 2 пр.
