摘　　要：全球气候变暖已经成为一项世界性的环境问题,越来越受到世界各国的关注。CO2是引起全球变暖的主要原因,有在短期内改变气候的可能。现今各国都在研究降低CO2排放的措施,希望能够开发一种易于工业化实现的吸收剂。CaO具有高的CO2吸附容量、低的制备成本、较长的使用寿命及良好的抗磨特性而成为优选的高温CO2脱除剂。主要分析CaO颗粒表面孔的结构和分布、烟气中水蒸气和SO2对CaO吸收性能的影响,为CaO吸收CO2性能的改善提供依据。Nowadays global warming already became an item of worldwide basis environment problem. CO2 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 industrialization easily. Because CaO has the high capacity of CO2 adsorption, low preparation cost, long service life and has good anti-abrasion characteristic, becomes CO2 absorption in high temperature. It mainly analyzed the distribution and structure of pore on the surface of CaO particle and exposited that the steam and SO2 in fuel gas contributed to CaO absorption performance.
