| 摘 要： | 文章研究在聚乙二醇-300(PEG-300)液相氛围下膨胀石墨对氮氧化物的去除。分别进行了反应物初始浓度、吸附剂用量、温度、流速等因素试验,考察其对氮氧化物去除效率的影响,结果表明:流速控制在0.5 L/min,初始浓度为0.5 mol/L,添加0.15 g膨胀石墨于20 mLPEG-300中,采用两级吸收在0℃下反应1 h,对氮氧化物的去除率可以达到90.03%,去除量可达474 mg/g,吸收剂简单易制,工艺简单,物耗低。

| Abstract: | Removal efficiency of nitrogen oxides by using expanded graphite in polyethylene glycol(PEG-300)atmosphere was studied.Effects of the initial concentration,dosage of adsorbent,temperature and velocity on removal of nitrogen oxides were discussed.Results indicated that nitrogen oxide removal reached over 90.03% and removal quantity reached to 474 mg/g on under the conditions of velocity 0.5 L/min,initial concentration 0.5 mol/L,and 0.15 g expanded graphite in 20 mL PEG300 at 0 ℃ for 1 h.The absorbent is easy to prepare,with simple process and low material consumption. |
