The invention relates to a process for regenerating the adsorbers of adsorber stations in the crude gas stream of installations for obtaining gas products from synthesis gas with the aid of a cryogenic gas separation unit. A part-stream from the purified synthesis gas stream, which is taken off downstream of the adsorber station but upstream of its cryogenic separation and is fed to the adsorber to be regenerated, is used as regeneration gas. The laden regeneration gas is either fed back to the crude synthesis gas stream upstream of the CO.sub.2 scrub, admixed to a product stream or removed from the installation.
