Abstract: A process for producing a hydrogen-carbon dioxide gas includes isolating CO2 from gas mixtures having a volume fraction of CO2 in the range from 0.01% to 20% using an adsorber and desorption of the CO2 using a heated hydrogen-containing gas stream in a desorber. The process also includes adjusting the CO2 volume fraction of the hydrogen-containing gas stream to the target content using a cycle gas system. The heated hydrogen-CO2 gas mixture is completely or partially passed through one or more desorbers thereby increasing the CO2 volume fraction in the hydrogen-CO2 gas mixture until achievement of a target value.
