本文研究了O2/CO2方式下钙基吸收剂在脱硫过程中微观结构的变化。研究结果表明，不同浓度的CO2对孔隙结构的影响完全不同；且提高温度有利于改善高浓度CO2气氛下钙基吸收剂煅烧后的孔隙结构，较之空气气氛，高浓度CO2气氛更有利于高温下炉内喷钙脱硫。

This paper reports on a study of microstructure changes of calcium-basedsorbent during desulfurization in O2/CO2 mixture. It's found thatpronounced influence on microstructure of calcium-based sorbent lies betweenhigh CO2 concentration and low CO2 concentration. The results indicatethat high CO2 concentration is better for capture of SO2 compared toair condition at high temperature accounting for minimizing sintering of CaOand plugging of reaction product CaSO4.
