本工作以活性炭模拟烟炱研究了其水悬浮液中二氧化硫的催化氧化。发现反应分两步进行,第一步是快速氧化过程,第二步是慢速氧化过程,后者的动力学方程为: In this work, the catalytic oxidation of sulfur dioxide in aqueous suspensions was studied using activated carbon simulated soot. The reaction was found in two steps, the first step is the rapid oxidation process, the second step is the slow oxidation process, the latter kinetic equation:
