摘要
在开放空间中利用玻璃片采集柴油燃烧火焰不同高度下的烟尘颗粒物,通过扫描电子显微镜(SEM)、X射线光电子能谱(XPS)和拉曼光谱分析烟尘颗粒的理化特性,结果表明:烟尘中碳、氧元素以无定形C、C-C、C-O、-COOH和吸附O等多种状态结合;随着采样高度的增加,烟尘中无定形C的含量呈现增大的趋势,无序化程度增强。
The small scale diesel combustion experiments were conducted in open space,and the glass sheets were used to collect the soot particles at different height of the flame.The physical and chemical properties of soot particles were explored by scanning electron microscopy ( SEM),X-ray photoelectron spectroscopy ( XPS) and Raman spectra.The results show that the carbon and oxygen elements in the soot are combined in various states such as amorphous C,C-C,C-O,-COOH and adsorption O.With the increase of sampling distance,the content of amorphous carbon and the degree of disorder in the soot show an increasing trend.
