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

Carbon dioxide capture from air (CO2 similar to 400 ppm) on powder Ce0.8Zr0.2O2 solid solution and subsequent conversion to dimethyl carbonate is described. The process includes three steps, namely (i) adsorptive enrichment of CO2 on the oxide surface, (ii) transformation under mild conditions (p = 1 bar; T = 70-110 degrees C) by subsequent gaseous methanol feeding in inert gas, and (iii) desorptive release of the products by treatment with pure inert gas.
