ABSTRACT OF THE DISCLOSURE Hydrogen and carbon monoxide are each separately recovered in high yield from a multicomponent gas stream containing these compounds to- gether with carbon dioxide and a zero to minor amount of one or more gaseous components from the group consisting of nitrogen, methane, water vapor and C2-C6 hydrocarbons, by a process wherein the multicomponent gas stream, such as that obtained by steam methane reforming, is initial- ly treated in a pressure swing adsorption unit to remove water and CO2, and the obtained effluent freed of CO2 and water is then further sub- jected to (1) cryogenic fractionation to condense CO and to (2) hydrogen purification by selective adsorption (in either order) to recover high purity carbon monoxide and essentially pure hydrogen. The CO2-laden adsorbent is regenerated by purging with a H2O and CO2-free waste gas stream from the hydrogen purification adsorbent bed or from the cryogenic fractionation or from both of these.
