采用X射线光电子能谱(XPS)对中国和澳洲褐煤进行分析,XPS全图分析表明,胜利褐煤成分较为混杂,检测到C、O、Si、Al和Na元素;Loy Yang褐煤只检测到C和O元素,样品相对纯净。2种褐煤碳元素形态较为接近,不同形式碳元素含量由高到低依次为C-C、C-O、C=O和O=C-O。氧元素分布差别较大,胜利褐煤中C-O占绝大多数,C=O和O=C-O含量都很低;而Loy Yang褐煤中,O=C-O和C-O含量较为接近。
X-ray photoelectron spectroscopy (XPS) was used to analyze the brown coal in China and Australia. XPS analysis showed that the composition of Shengli lignite was mixed and C, O, Si, Al and Na elements were detected. Loy Yang lignite only detected C and O element, the sample is relatively pure. The carbon forms of two lignites are similar, and the contents of carbon in different forms are C-C, C-O, C = O and O = C-O from high to low. Oxygen elemental distribution is quite different. C-O accounts for the vast majority in Shengli lignite with low contents of C = O and O = C-O, while O = C-O and C-O in Loy Yang lignite are close to each other.
