The kinetic data was measured with a non gradient reactor, The parameters of the model equation were calculated based on experimental results by the Powell non linear regression method: k 1=0 152e -62073RT , k 2=8.18e -2384RT ,k 3=0.221e -18949RT .

• 采用内循环无梯度反应器测定了SO2 氧化反应动力学数据 ；并利用 Powell法对动力学模型进行参数估值 ；得到 :k1=0 .；15 2 exp(- 6 2 0 73/ RT)；k2 =8
