ABSTRACT:
Separation and individual recovery of high purity hydrogen and carbon monoxide from a mixed gas stream containing these compounds in association with carbon dioxide and one or more minor components such as particularly methane, is achieved by pressure swing adsorption to remove contained carbon dioxide from the charged gas, and further treatment of the CO.sub.2 -freed gas product by a sequence of steps utilizing (a) pressure swing adsorption and (b) selective permeation through a series of semi-permeable membranes, which steps (a) and (b) are carried out in either order of sequence.
