Optimisation of Cu impregnation of MOF-74 to improve CO/N and CO/CO separations.

Carbon monoxide (CO) purification from syngas impurities is a highly energy and cost intensive process. Adsorption separation using metal-organic frameworks (MOFs) is being explored as an alternative technology for CO/nitrogen (N) and CO/carbon dioxide (CO) separation. Currently, MOFs' uptake and selectivity levels do not justify displacement of the current commercially available technologies.
