| 摘要 |
Carbon monoxide is recovered as the intermediate component of a reformer effluent containing hydrogen, carbon monoxide and carbon dioxide in a pressure swing adsorption system by the introduction of a gas displacement step before, simultaneous with or subsequent to pressure equalization between beds of a multi-bed adsorption system, with a cocurrent depressurization step being employed to recover said CO product. The carbon dioxide-rich countercurrent depressurization and/or purge effluent is recycled to the reformer for reaction with natural gas or other feed gas, with no carbon dioxide scrubbing step being employed before passage of the reformer effluent to the pressure swing adsorption system.
