Abstract：Inthispaper，theanti-sinteringabsorbent waspreparedbyusingcarbideslagascalciumsoure，citricacidasmodiie，and aluminumnitrateasdopantTeaterialserecaracterizedbX-aydifractiotrogadsortionandaningelectroicro copy. The cyclic adsorption properties of CO2 were tested by thermogravimetric analyzer. The results show that compared with p-CS andSG-CS adsorbents，CS9oA10 adsorbent doped witha mass fraction of 10% Al can observe obvious Ca3Al2O6 diffraction peak， and have more mesoporous structure，larger specific surface area （9.59m2/g） ）and pore volume （0.017m3/g） ）.Due to the presence of a largeamount of highly stableinert skeleton component Ca3Al2O6 in theaccumulated granules of CaO，the Cs9oA10 adsorbent exhibits excelentantsinteringability.After30longccles，themicroscoic morphologyandporestructureof teadsorbentrmindbasically unchanged，and the CO2 adsorption capacity only decreased by 0.2g/g compared to the initial cycle，still reaching 0.33g/g The carbonation conversion rate was 54.97% ，showing high structural and adsorption stability.
