摘要
NO对人体健康及环境危害较大。但现行湿法脱硝技术氧化效率普遍不高,本研究以准Cu-BTC为研究对象,SEM结果显示其为均匀分散的八面体结构,FT-IR及XRD结果表明其仍保留着MOFs有机骨架结构。NO去除性能评价结果表明准Cu-BTC在气体流速为100 mL/min, NO初始浓度为300 mg/kg,投料比为1:100,温度为60℃,pH为5~8时催化效果最佳。研究结果表明准Cu-BTC不仅具有更好的水/热稳定性,也具有更佳的催化性能,可有效提高湿法脱硝的氧化效率,为工业化湿法脱硝提供了新思路。
NO is harmful to human health and environment. However, the current wet denitrification technology generally has low oxidation efficiency. Quasi-Cu-BTC was used as catalyst for Fenton-like system. SEM result showed that it had a highly dispersed and uniform octahedral structure, and FT-IR and XRD results showed that it retained the organic skeleton structure of MOFs. The result of NO removal test showed that the catalytic effect of Quasi Cu-BTC was best when the gas flow rate was 100 mL/min, the initial concentration of NO was 300 mg/kg, the feed ratio was 1:100, the temperature was 60 ℃ and pH was 5~8. The study revealed that quasi-Cu-BTC not only had better water/thermal stability, but also had better catalytic performance, which can effectively improve the oxidation efficiency of wet denitrification, and provided a new idea for industrial wet denitrification.
