Beschreibung
Zusammenfassung:	A process is described for generating hydrogen from hydrocarbons. The hydrocarbons are subjected to partial oxidation, the gaseous fraction thus obtained is fed to a CO shift conversion, and the acid gases are removed by scrubbing. In order to obtain an H2 product having a purity of at least 99% by volume, without reducing the yield, it is proposed to remove the sulphur compounds in a first absorption stage by means of an organic, physically acting solvent, to subject the desulphurised gas to selective catalytic CO oxidation and then, in a second absorption stage, to remove CO2 by means of an organic, physically acting solvent.
