摘　　要：煤并不是一种均一的物质,煤中的有机组成由三种显微组分组成:镜质组、壳质组和惰质组。我国华南晚二叠世树皮残植煤以高氢含量、高生油潜力为特点,主要的壳质组显微组分为树皮体,关于此显微组分的煤岩研究已证明高含量的树皮体是该煤种具有以上特点的主要因素,因此对树皮煤的研究具有更大的科学意义,而将显微组分从树皮煤中分离出来是一切研究的前提。以我国华南二叠世树皮煤为研究对象,对树皮煤中的各显微组分结合密度梯度离心技术进行煤岩显微组分的分离实验,探讨与分析树皮煤中各显微组分的密度分布特征以及根据此特征将树皮体和其他显微组分分离制样。Coal is not a homogeneous material,organic components in coal by three kinds of maceral composition： vitrinite,EXINITE and vitrinite.China＇s Southern China Late Permian bark liptobiolite in high hydrogen content,high hydrocarbon potential is a characteristic,EXINITE microscopic group mainly consists of barkinite,this research on coal macerals has proved that the high content of the bark is the main factor of coal has the above characteristics,so study of tree bark coal has great scientific significance,and from the bark coal macerals separating is a prerequisite for all research.Taking Southern China Permian bark coal in China as the research object,on the microstructure of bark coal is in the combination of density gradient centrifugation technique for separation of coal macerals,the discussion and analysis of the distribution characteristics of macerals of coal in the bark and according to the characteristics of the bark and other maceral separation and sample preparation.
