摘　　要：为了更准确地了解树皮体的生烃潜力,课题组与德国Horsfield教授和Radke博士在德国JUELICH国家研究中心对从贵州大河煤矿采集的一组树皮体样品进行了开放热解分析。根据试验得出:相对于煤的其它显微组分,树皮体的热解产物最多,达330mg/gTOC;在Later三角图中,树皮体位于Ⅰ、Ⅱ型干酪根的结合处之外,与许多海相Ⅱ型和Ⅱs型干酪根相同;树皮体热解产物主要为中链化合物,可产生较多的液体油,更适合液化或作为煤变油的原料利用。Bark coal has special geochemical characters. ＂Barkinite＂ was analyzed for finding out its ability of generating hydrocarbon in the laboratory of ICG-4, FZ-Juelich, German. It can be concluded that： firstly, ＂barkinite＂ gave the highest pyrolysis yield overall（330mg/g TOC） ; secondly, ＂barkinite＂ is the closest to the adjacent field for type Ⅰ and Ⅱkemgens in the ternary diagram of Larter; it is the same as many marine type Ⅱ and type IIS kerogens; Third, the pyrolysis products of ＂barkinite＂ is the main intermediate chain compounds, and it has a higher capacity for generating petroleum liquids.
