| 中文摘要 |
| 介绍了两种催化剂PCN-1,PCN-2型对含氮有机物如N,N-二甲基甲酰胺(DMF)、正丁胺、环己胺、苯胺、硝基苯等深度氧化的活性及控NOx能力。实验结果表明,由PCN-1、PCN构成的双催化剂处理DMF或DMF与甲苯、DMF与甲乙酮的混合蒸气,其氧化活性和控NOx能力比单一催化剂为好。在240—300℃温度范围即可完全氧化,控NOx率达98%以上,净化气无色无臭。本工艺可用于PU合成革生产线烘道排气的净化处理。 |
| 英文摘要 |
| Deep oxidation of volatile organic nitrogen pollutants such as N-dimethylformsmide (DMF) and butylamine could be achieved under the catalysis of PCN-1 and PCN-2. The activtiy of the two catalysts were studied. Experiment results show that the effect of a double bed composed of PCN-1 and PCN-2 is better than any single catalyst bedfor purifying DMF or the mixed vapors of DMF with toluene or methylethylacetone. The vapors could be completly oxidized and basically no NOx came out at working temperature ranging from 240 to 300℃. The purified stream was esentially odourless and colourless This technology proved to be suitable for the purification of exhaust gas in the process of producing PU synthetic leather. |
