Abstract: Through the thermal simulation on original coal rocks in Jurassic system and the coal with different mediums from 250 ℃ to 550 ℃, with a stepwise heating stage of 50 ℃,the characteristics of their gaseous and liquid products are systematically analyzed. The result shows that the process of coal generation hydrocarbon is comprehensive and complicated. Oil and gas generated from the coal rock is related to its environment,e.g.the water and clayminerals can help this process.The yielding rate of gas products is increased with the rising temperature.Different mediums added in the simulation experiment can effectively reduce the temperature of hydrocarbon generation,and they are especially helpful to liquid hydrocarbon generation.
