【摘要】 吸附了SO2 的载硫活性炭 ,采用微波辐照法进行活性炭解吸及再生得到高浓度SO2 产品气 ,以达到生产高浓度的制酸合格原料气SO2 的目的 ,为低浓度SO2 回收利用提供了一条有效途径。作者针对微波功率、载气量、活性炭量、再生时间及次数等影响SO2 解吸的因素进行了实验研究。实验结果表明 :在微波功率 70 0W、载气流量 0 .3L /min、饱和活性炭质量 8g以上、再生时间 3min的条件下 ,SO2 产品气浓度可达90 %以上。更多还原

【Abstract】 In order to produce high concentration SO₂ product gas,the method of microwave desorption of SO₂-loaded activated carbon was studied.The experiments on influences of operating conditions on SO₂ desorption such as the （microwave） power,gas-loaded quantum,activated carbon quantum,regeneration time and times of activated carbon were carried out.The optimal operating conditions were got.Under the conditions of microwave power 700 W,feed gas flow rate 0.3 L/min,irradiation time 3 min,concentration of SO₂ product gas can reach 90% with 8 g activated carbon.更多还原
