Adsorptive Capture of CO2 from Air and Subsequent Direct Esterification under Mild Conditions

Carbon dioxide capture from air (CO 2 ∼ 400 ppm) on powder Ce 0.8 Zr 0.2 O 2 solid solution and subsequent conversion to dimethyl carbonate is described. The process includes three steps, namely (i) adsorptive enrichment of CO 2 on the oxide surface, (ii) transformation under mild conditions ( p = 1 bar; T = 70–110 °C) by subsequent gaseous methanol feeding in inert gas, and (iii) desorptive release of the products by treatment with pure inert gas.
