Abstract：The aim of this study was to investigate the effect of microwave-assisted heating technique on the reactive adsorption performance and adsorption capacity stability CaCO3 combinations were prepared, and the adsorption performance and adsorption capacity stability were evaluated using a thermogravimetric analyser (TGA), and the effects of different SiC contents on the adsorption capacity stability of the adsorbents were further investigated by microwave-heated tube furnace. The experimental results showed that the optimal adsorbent particle size combination was 150 μm SiC and 0.06μm CaCO3, in which the adsorbent with 150 μm SiC particle size and 20% content increased the adsorption capacity of microwave-assisted heating compared with conventional electric heating by 0.47mol/kg and 0.63 mol/kg after the 14th and 20th cycles, respectively. In addition, the specific surface area test results showed that microwave-assisted heating helped to maintain the pore size structure of the adsorbent and reduce the sintering phenomenon, thus significantly improving the stability of the adsorption capacity. The study showed that the microwave-assisted heating technique could effectively improve the adsorption performance and cyclic stability of CaO-based CO2 adsorbent, which was better than the traditional electric heating method.
