The separation and recovery of carbon monoxide (CO) from blast furnace gas (BFG) mixtures is an important issue, as CO is a key substance in the petrochemical industry. We developed a series of Cu(I)-impregnated MIL-100(Fe) (Cu(x)@MIL-100(Fe)) with varied Cu loadings through a facile Cu(I)-loading method that does not require high-temperature thermal treatment. Among these, we found that Cu(0.5)@MIL-100(Fe) is the optimal material, with a high CO/CO2 selectivity (15.4) and large working capacity (0.38 mmol/g). This material showed very high CO/CO2, CO/N2, and CO/H2 selectivities (33.3, 106.4, and 98.4, respectively) for gas mixtures with a typical BFG composition, excellent CO separation from a simulated BFG mixture (CO/CO2/N2/H2 = 22:20:55:3 vol.%) under dynamic flow conditions, and reasonable air stability. These results show that Cu(0.5)@MIL-100(Fe) is an efficient adsorbent for the recovery of CO from BFG.
