Abstract
A process for recovering hydrogen products from a hydrogen/carbon oxide synthesis gas wherein removal of carbon oxides is accomplished in a pressure swing adsorption unit, by operating the pressure swing adsorption unit until carbon oxides break through into the effluent from the pressure swing adsorption unit, followed by passing the effluent from the pressure swing adsorption unit through a methanator to remove breakthrough carbon oxides from the pressure swing adsorption effluent.
