Abstract
Porous carbons loaded with CaO and MgO were prepared through a one-step process from mixtures of poly(ethylene terephthalate) and dolomite mineral. Obtained hybrid materials were examined as sorbents for CO2 gas contained in air. The influence of pore structure, loadings of the oxides, moisture, and temperature on the efficiency of gas removal is presented and discussed. Performance of the materials during CO2 capture was confirmed to be influenced by all mentioned factors. As a rule, efficiency of CO2 removal increased along with loading of the oxides. CO2 uptake increased also with moisture content and temperature of the bed. On the basis of attained results, optimal parameters for operational use are suggested and probable mechanisms of the CO2 removal from dry and humid air are proposed. Cyclic sorption–desorption experiments confirmed capability of the material for several-times use. Superior performance of the hybrid materials over a mixture of CaO and MgO is confirmed and discussed.
