Test study of disposing nitrogenous VOCs by catalytic oxidation technology
-
摘要: 对某分子筛生产企业焙烧炉排放的废气开展催化氧化侧线试验研究,考察了在不同反应温度和催化剂床层空速条件下,催化氧化对烃类、含氮VOCs以及CO的去除效果,并重点考察了不同试验条件下NOx的产生量。结果表明:在催化剂的作用下,催化氧化技术能在275~325 ℃的较低温度下有效去除废气中的非甲烷总烃、CO和含氮VOCs等有害组分,污染物去除率达95%以上,且NOx可达标排放。Abstract: A sideline test study on catalytic oxidation of waste gas discharged from the calcining furnace of a molecular sieve company was carried on. The removal effect of hydrocarbons, nitrogenous VOCs and carbon monoxide under different reaction temperatures and catalyst bed space velocities was studied, focusing on the production of nitrogen oxides under different test conditions. The results show that under the action of catalyst, the catalytic oxidation technology can effectively remove the non-methane hydrocarbons, carbon monoxide and nitrogenous VOCs and other harmful components at low temperature 275 to 325 ℃. The pollutants removal rate can be more than 95%, and the NOx emission can reach the national standard.
