基于热重分析法（TGA）测试2种钙基吸收剂的CO2循环特性，引入多参数线性回归统计分析方法，确定了反应参数（循环次数、碳酸化反应时间、煅烧温度及煅烧气氛）与循环反应速率和转化率之间的关系，引入评价函数F推导了各参数对吸收剂循环吸收特性的影响程度．结果表明：通过对不同反应机理阶段分别建立回归方程，准确描述了不同参数条件下钙基吸收剂的CO2吸收循环过程；在化学反应控制阶段，反应时间对吸收效率的影响最为显著，而进入扩散反应控制阶段后循环反应次数成为决定因素．

The cyclic CO2 capture behavior of two calcium-based sorbents were tested based on thermo gravimetric ana[ysis method (TGA). Using linear regression statistic analysis, the relationship was deter- mined between the reaction parameters (including cycle number, carbonation reaction time, calcination temperature and calcination atmosphere) and the cyclic reaction rate and conversion rate. Evaluation func- tion F was introduced to deduce the effect of each independent parameter on the cyclic capture behavior of sorbents. Result show that the cyclic CO2 capture process by calcium-based sorbent can be accurately de- scribed under different parameter conditions through establishment of regression equations for different phases of reaction mechanism respectively. The effect of reaction time on the capture efficiency is most sig- nificant during chemical reaction control phase, and the cycle number turns to be dominant after diffusion reaction control phase is initiated.
