摘要
采用吸附存储/低温等离子体催化技术降解甲苯,分析了催化剂M/13X-Al(M为Ag、Fe、Cu)、放电电压、甲苯吸附量对低温等离子体氧化效果的影响。结果表明:Ag/13X-Al具有较大的穿透吸附量与较高的COx(CO2、CO)产率。当放电电压由12kV升高至22kV,活性粒子大量增加,COx产率从32%提高至71%;而当甲苯吸附量增加,单个甲苯分子与活性粒子的碰撞几率降低,COx产率急剧下降。
Adsorption storage/low temperature plasma catalysis technology was used to degrade toluene.The effect of catalysts M/13 X-Al(M was Ag,Fe,Cu),discharge voltage,and the adsorption amount of toluene on the low temperature plasma oxidation performance were investigated.The results showed that Ag/13 X-Al had higher adsorption breakthrough capacity and COx(CO2,CO)yield.When the discharge voltage increased from 12 kV to 22 kV,the active particles increased significantly,and the COx yield increased from 32% to 71%.However,when the adsorption amount of toluene increased,the probability of collision between individual toluene molecule and active particle decreased,and the COx yield decreased sharply.
