摘要

经初步筛选选定以聚丙烯腈为原料加工而成的两种活性炭纤维毡 (ACF)

研究了其本体和经硝酸浸渍处理后脱除NO的性能

表明ACF经硝酸处理后脱除NO的性能有所提高 .在ACF上进行的程序升温脱附试验表明

ACF经硝酸浸渍处理后对O2 、CO和NO的吸附性能均强于未处理的

唯有CO2 相反 .根据文献与实验现象

认为NO在碳纤维上的解离吸附是此反应的控制步骤

反应的初级产物为CO2

并按一级反应处理

得到了NO与碳反应的反应速率与温度的关联式 .研究表明经硝酸浸渍处理后的ACF脱除NO的性能恒优于未处理的 .

Abstract

Two kinds of activated carbon fibers (ACF) made from polyacrylonitrile were selected in order to study their NO reduction properties. Experimental results showed that the NO reduction activity of HNO 3 dipped ACF is higher than that of non-treated one. In order to know the adsorption properties of various oxygen containing gases on ACFs

TPD experiments over ACF showed that the adsorption abilities of CO

NO and O 2 on HNO 3 dipped ACFs are higher than that on non-dipped ACFs

but CO 2 has a reverse result. According to literature and experimental results

we suppose that dissociative adsorption of NO on ACF is the rate controlling step of this reaction

and the primary product of this reaction is carbon dioxide.On the basis of this assumption

a first order kinetic equation was used to treat experimental data

and Arrhenius equations for NO reduction over four different ACFs were obtained.NO reduction activity of HNO 3 dipped ACF was always higher than that of non-dipped one.
