Abstract
The present invention provides a process for recovering gaseous hydrogen and gaseous carbon dioxide from a mixture of hydrocarbons by utilizing a system that includes a reformer unit, an optional water gas shift reactor, and a pressure swing adsorption unit in conjunction with a carbon dioxide purification unit such as a cryogenic purification unit or a catalytic oxidizer. In this process, purified COfrom the COpurification unit is used as a co-feed/co-purge in the pressure swing adsorption unit in order to produce a COtail gas that includes a higher concentration of CO.
