Zusammenfassung:The invention discloses a method for preparing a carbonation-resistant calcium-based absorbent with an impregnation method. CaO solids are ground into powder; the CaO powder and aluminum nitrate nonahydrate are dissolved in isopropanol and distilled water together, the materials are stirred and heated, obtained solids are ground into powder, the powder and ferric sulfate nonahydrate are dissolvedin isopropanol and distilled water together, the materials are stirred and heated, obtained solids are ground into powder, a proper amount of distilled water is added, and the powder can be conveniently twisted into small balls; the small balls are calcined for 4 hours, and the product is obtained. The molecular formula of the carbonation-resistant calcium-based absorbent is FexOy/CaO-Ca12Al14O33,the cyclic carbonation stability is obviously optimized, and the capacity of cyclically absorbing and releasing CO2 is improved. 本发明公开了种利用浸渍法制备耐碳酸化钙基吸收剂的方法,将CaO固体碾磨成粉末;将CaO粉末与九水硝酸铝起溶解于的异丙醇和蒸馏水中,搅拌加温,将得到的固体碾磨成粉末,再将粉末与九水硝酸铁起溶解于
