摘　　要：以固定床吸附操作线方程为基础,建立了化学反应存在下固定床糠醛渣活性炭吸附烟气SO2的吸附动力学计算模型。采用数值计算方法求解,并利用文献数据检验,表明床层负荷分布及透过曲线模型计算方法可以为设计提供参考。Based on the equation of adsorption operating line, a kinetic model for desulfurization by the activated carbon fixed bed with chemical reaction was developed. Numerical solutions of the adsorption mathematical model were obtained and compared with experimental data in literatures. It indicated that this calculating method suggests a valuable reference for design.
