中文摘要：

氧原子作为煤中最丰富的杂原子,C-O官能团的形态对煤的性质有重要影响。为了研究煤岩显微组分的含氧官能团,对手选高纯度镜质组和惰质组进行了XPS分析和化学计算。结果表明,煤岩组分的元素组成以C、O为主,含少量的N和无机矿物元素。其中的氧主要以-OH、-O-、COO-和SiO_2形式存在。C-C、C-H、C-O单键和COO-是碳的主要存在形式。镜质组中的脂肪族侧链和-OH基团较多;惰质组中-O-的原子浓度明显高于镜质组,而COO-略多于镜质组。镜质组表面总极性含氧官能团数量更多。研究结果有助于全面认识煤的结构和性质。

英文摘要：

In this study,X-ray photoelectron spectroscopy（XPS） is used to investigate the functional group of hand-picked macerals with higher purify.Different from previous studies,oxygen functionality has been determined by resolution and calculation of C1s XPS spectra.It shows that carbon,oxygen,a little of nitrogen and mineral are the chemical components in macerals.Also,-OH,-O-,COO-and SiO2 are main forms of oxygen;and carbon exists in the forms of C-C or C-H,C-O,and COO-.The vitrinite has higher content of C-C or C-H than inertinite.The phenolic hydroxyl contents of vitrinite are more than that of inertinite.There are more-O-and COO-in inertinite.Polar oxygen contained group in vitrinite is even much more.The conclusions in this study are useful for understanding the structure and property of coal.
