针对活性炭烟气脱硫过程，以吸附质浓度沿床层分布曲线实验为基础，对活性炭脱除SO2的催化反应速率的影响因素进行了探讨.研究发现SO2质量浓度和CO2体积分数对活性炭催化反应速率有显著影响. SO2质量浓度对活性炭催化反应速率影响最大，随着SO2质量浓度升高催化反应速率将显著增加，但高SO2质量浓度下催化反应速率将不再增加；体积分数在15%以内的CO2对催化反应速率呈线性抑制，使得活性炭催化反应速率降低约30%；烟气线速度在0.14~0.3 m·s-1之间变化时对催化反应速率的影响效果不大。

According to flue gas desulfurization processes with activated carbon, several factors affecting the catalytic reaction rate of activated carbon for flue gas desulfurization were investigated on the basis of the experiment of adsorbate concentration curves along the bed. It is found that SO2 concentration and CO2 volume fraction have significant influences on the catalytic reaction rate, and SO2 concentration is the primary factor. With increasing SO2 concentration, the catalytic reaction rate increases significantly, but it does not increase at high SO2 concentration. While the CO2 volume fraction increases from 0 to 15%, the catalytic reaction rate decreases by 30% linearly, indicating that CO2 plays a linear inhibition role in the catalytic reaction. The flue gas velocity between 0.14 m·s-1 and 0.3 m·s-1 has no significant effect on the catalytic reaction rate.
