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.
