Effluent gas streams for steam reforming, partial oxidation or coal gasification operations are advantageously treated in shift conversion, scrubbing and pressure swing adsorption units for recovery of a purified, hydrogen-containing product gas stream. By recycling a portion of the waste gas removed from the pressure swing adsorption system to the shift conversion unit and/or to the effluent gas generation operation, enhanced product recovery is achieved without the necessity for employing low temperature shift or for achieving essentially complete remo...
1. An improved process for the production of a hydrogen-containing product gas consisting essentially of: (a) generating an effluent gas stream comprising hydrogen, carbon dioxide, carbon monoxide and water vapor; (b) upon cooling said effluent stream to about 350° C. -400° C., subjecting said effluent stream to at least a high temperature catalytic water gas shift conversion, thereby converting most of the carbon monoxide in said effluent stream to additional hydrogen and carbon dioxide; (c) scrubbing at least a major portion of the carbon dioxide ...
