Abstract:
The present invention relates to a method for the combined production of hydrogen and carbon dioxide from a hydrocarbon mixture, in which the hydrocarbon mixture is reformed to produce a syngas which is cooled, then enriched with H2 and CO2, optionally dried, and treated in a PSA hydrogen purification unit to produce hydrogen, the PSA offgas being treated to capture the CO2 and to supply an offgas. This offgas is again treated to supply a stream enriched with H2 and CO2 which is returned to the PSA, where it constitutes a second feed distinct from the main feed.
