【摘要】 以纯ＳＯ２及燃煤电厂烟气作实验气，利用积分法固定床ＣＦＢ方式进行了ＤＳ－Ⅰ型催化剂与活性炭催化性能的对比试验，对不同还进行了不同烟气温度、ＳＯ２浓度、湿度、烟气流速等工艺参数对ＤＳ-Ⅰ型催化剂催化性能的影响试验。对不同催化剂进行优化组合，可在除尘器后直接脱硫、脱氮，其脱硫率达８６％、脱氮率达６８％。催化剂经再生，可反复使用。更多还原

【Abstract】 With pure SO₂ and flue gas from coal-fired power plant as experimental gases, a comparison experiment on catalytical function of DS-Ⅰ catalyst and activated carbon was carried out. Influence of temperature, SO2 concentration, humidity and gas flow rate on DS-Ⅰ catalytical function was also investigated. It was found that 86% SO2 and 68% NOx removal efficiency could be obtained by catalyst optimum combination if a removal process was conducted directly be- hind the precipitator. The catalyst can be used repeatedly after regeneration.更多还原
