With the increasingly serious problem of climate warming in recent years, CO2 capture technology has been widely concernedby countries all over the world. One of the effective methods to reduce CO2 emissions is to capture CO2 after combustion. Alkali metal salt modified MgO-based adsorbents were synthesized by hydration impregnation method to obtain high efficientadsorbents in this study. The CO2 cyclic adsorption capacity test was carried out in a fixed bed experimental setup. Themicrostructure of the adsorbent was characterized by XRD, SEM and BET techniques. The adsorption properties and cyclestability of alkali metal salts modified MgO adsorbents were deeply studied. The results show that the adsorbent with 10wt% K2CO3-MgO has the best adsorption performance and cyclic stability. The initial adsorption capacity is 89 mg/g·sorbent,and the adsorption capacity of the 15th cycle is 63 mgCO2/ g·sorbent. 10 wt% K2CO3-MgO adsorbent has the largest specificsurface area, and K2CO3 doping of alkali metal carbonate can effectively improve the CO2 adsorption capacity and cyclicstability of the adsorbent.
