Abstract (en)
[origin: WO2021078614A1] The present invention relates to a method for producing hydrogen, which method is characterized in that: in a first stage, hydrocarbons are decomposed into solid carbon and a hydrogen-containing gaseous product mixture; the hydrogen-containing gaseous product mixture, which has a composition, with respect to the main components CH4, N2 and H2, of 20 to 95 vol% H2 and 80 to 5 vol% CH4 and/or N2, is removed from the first stage at a temperature of 50 to 300 °C and is fed, at a temperature that differs from this exit temperature by at most 100 °C, into an electrochemical separation process; and in this second stage, the hydrogen-containing product mixture is separated, in the electrochemical separation process at a temperature of 50 to 200 °C, into hydrogen having a purity of > 99.99 % and a remaining residual gas mixture.
