摘要：通过测定不同时间活性炭上的ＳＯ３蓄积量，以ＬａｎｇｍｕｉｒＨｉｎｓｈｅｌｗｏｏｄ方法进行了动力学方程的推导，发现整个过程可分为具有不同反应机理的两个阶段．在ＳＯ３蓄积量小的情况下，ＳＯ３对ＳＯ２和氧的吸附不产生影响；在ＳＯ３蓄积量达到一定限度后，则成为一种阻抑物质．同时还获得了吸附平衡常数和反应速率常数．
From Langmuir Hinshelwood method,the reaction kinetics equation was derived.It was proposed the whole process was divided into stages with different mechanisms,in the early stage of the process with low SO 3 accumulation,SO 3 had no effect on the adsorption of SO 2 and O 2.However when the amount of SO 3 exceeded a critical value,it acted as an inhibiting substance on the adsorption of the reactants thus substantially deceased the reaction rate.
