Abstract
Removal of CO2 from CO gas mixtures is a necessary but challenging step during production of ultraĆ¢ pure CO as processed from either steam reforming of hydrocarbons or CO2 reduction. Herein, two hybrid ultramicroporous materials (HUMs), SIFSIXĆ¢ 3Ć¢ Ni and TIFSIXĆ¢ 2Ć¢ CuĆ¢ i, which are known to exhibit strong affinity for CO2, were examined with respect to their performance for this separation. The singleĆ¢ gas CO sorption isotherms of these HUMs were measured for the first time and are indicative of weak affinity for CO and benchmark CO2/CO selectivity (>4000 for SIFSIXĆ¢ 3Ć¢ Ni). This prompted us to conduct dynamic breakthrough experiments and compare performance with other porous materials. UltraĆ¢ pure CO (99.99 %) was thereby obtained from CO gas mixtures containing both trace (1 %) and bulk (50 %) levels of CO2 in a oneĆ¢ step physisorptionĆ¢ based separation process.
