活性碳纖維作還原劑降低NO實驗研究
摘要: 利用程序升溫反應(yīng)裝置(TPR),在微型反應(yīng)器中對國產(chǎn)各種活性碳 纖維(ACF)進(jìn)行了脫除NO的效果對比實驗,定量測定了在不同溫度下ACF與NO的反應(yīng)產(chǎn)物,并通 過程序升溫脫附(TPD)、熱重(TG)及掃描電鏡(SEM)的研究,初步探討了ACF宏觀反應(yīng)機(jī)理, 并考察了所選ACF在不同氣氛下的變化規(guī)律。實驗結(jié)果表明,聚丙烯腈基ACF脫除NO性能最佳。 Abstract: Five kinds of activated carbon fiber (ACF) were used in the reduct ion of NO as reducing agent.These samples were subjected to temperature programm ed reaction (TPR) in a flow microreactor.By use of thermogravimetry (TG), temperature programmed desorption (TPD) and scanning electron microscopy (SEM) ,the ACF was evaluated and selected successfully.The macrosco pic reaction mechanism of NO removal has been discussed.Moreover,the influences of O2,O2+CO,and temperature on NO reduction were examined.The test results show that NO concentration may be reduced effectively,and the best ACF w as prepared from polyacrylonitrile based activated carbon fiber. 作 者: 郭世永 張守臣 趙修仁 陳家驊 GUO Shi-yong ZHANG Shou-chen ZHAO Xiu-ren CHEN Jia-hua 作者單位: 郭世永,陳家驊,GUO Shi-yong,CHEN Jia-hua(大連理工大學(xué) 內(nèi)燃機(jī)研究所,)張守臣,趙修仁,ZHANG Shou-chen,ZHAO Xiu-ren(大連 理工大學(xué) 化工學(xué)院,)
