PRODUCTION OF HYDROGEN USING METHANATION AND PRESSURE SWING ADSORPTION

摘要

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 carbo n 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 effluen t.
