FIELD: chemistry.SUBSTANCE: invention relates to an apparatus for producing hydrogen. The apparatus has a reaction chamber surrounded by a pipe, in which a mixture of water vapour and carbon-containing material is converted by steam reforming, and a partition wall which is partially, selectively permeable for hydrogen, through which hydrogen formed during steam reforming can be continuously removed from the reaction chamber with high purity and at pressure below the pressure in the reaction chamber and higher than ambient pressure. Portions of the partition wall that are selectively permeable for hydrogen lie such that on the entire surface of such a portion between the reaction chamber and the hydrogen outlet side there is always a drop of partial pressure, wherein the partition wall consists of a plurality of thermodiffusion separating pipes connected to form a unit.EFFECT: obtaining high-purity hydrogen and low capital costs by excluding separation and/or compression of hydrogen.2 dwg |
