摘　　要：随着温室效应对全球气候的影响越来越显著,世界上将有更多国家关注温室气体的排放问题。温室气体中CO2的排放量最大,被认为是引起全球变暖的主要原因,有在短期内改变气候的可能。现今许多国家都在研究减排与隔离CO2的措施,希望能够开发一种高效、低成本的CO2吸收技术。相对于其它的吸收剂,CaO具有高吸附量、低制备成本、较长循环使用寿命及良好抗磨特性而成为优选的高温CO2脱除剂,CaO循环吸收CO2技术在工业操作中也较为简单。主要通过分析煅烧/吸收温度、添加剂、CaO颗粒内部孔结构和分布以及烟气中其它主要成分对CaO吸收性能的影响,为CaO吸收CO2性能的改善提供一定的理论基础。Global climate is more and more notable with greenhouse effect, more countries received the attention about it. CO2 is releasing the most Greenhouse gas which is the main cause that can make the whole world warm; it can change the climate in the short-term possibility. Nowadays many countries are studying reducing CO2 emission, hoping develop a new absorbent which is high-effect, 16w cost sorption technology. CaO is high capacity of CO2 adsorption, low preparation cost, long service life and has good anti-rubs characteristic, becoming CO2 absorption in high temperature. This article mainly analyzes temperature, additive, structure of pore on the surface of CaO particle and other component in fuel gas contributed to CaO absorption performance. It can provide a theoretical basis for improving the CaO absorption performance.
