abstract

• Abstract Mg, Zn, Mn, and Al oxide powders have been synthesized through chemical combustion and calcination methods to compare their CO2 capture performances. The characteristic properties of the adsorbents were evaluated by X-ray diffraction analysis, scanning electron microscopy, and N2 physisorption measurements. The porous γ-Al2O3 prepared through combustion with a BET-specific surface area of 192.1 m2/g, achieving a maximum gas adsorption capacity of 1.71 mmol/g at 60°C and 1.5 MPa. The MgO adsorbent performed poorly during CO2 capture, while that Zn and Mn oxides showed no CO2 adsorption. The results showed theoretical contribution to the field of separation science. © 2015 Springer International Publishing Switzerland.
