Abstract: Organic geo-chemical methods were utilizedto simulatethe hydrocarbon-generation modes of coal samples fromGuizhou Province. High temperature simulation experiment by quartz cuvette technique and microscope analysis by FTIR were utilized to estimate hydrocarbon-generation mode and potential of local coal mine in Panxian, Guizhou Province. The results indicate that, the kerogen of Panxian coals is of Ⅲtype; the heating product is mainly gas because of the simple component of kerogen; and the mass hydrocarbon producing temperature is about 300-350 ℃.

Key words: Panxian, Guizhou Province, coal generating hydrocarbons, hydrocarbon-generation potential, FTIR
