| 摘 要： | 单组分成烃热模拟实验已成为煤成烃研究的重要组成部分，煤显微组分分离是上述研究的重要前提。实验结果证明：单纯应用某一种方法效果往往不佳，而采用人工碎样→筛选法→浮选法（沉淀法）→高速离心法这一综合的显微组分分离方法，则可以获得高纯度的显微组分。

| Abstract: | Laboratory thermo-simulation to study the hydrocarbon generation from monmaceral has been the mainaspect of the research on ccal formed oil.The separation of coal maceral is the prerequisite for the work. It is almostimpossible to get a certain maceral with high purity by using just one of the methods for coal maceral separation. However,based on present experiments, it is proved that more pure maceral could be obtained by using muitiplemethods,such as screening, subsequently, float-sinking with density gradient centrifugtion technique. |
