Study of Longkou Oil Shale Pyrolysis Behavior with Bitumen as the Intermediate

Oil shale as the petroleum alternative is widely distributed in China, the total oil shale resources and potential shale oil resources are estimated at 719.937 billion tons and 47.644 billion tons, respectively. Shale oil and gas can be obtained through the pyrolosis of the oil shale. In order to study of the behavior of the pyrolosis of Longkou oil shale, bitumen as the intermediate products was referenced to the characteristics of the pyrolosis. The result showed that bitumen first output at the pyrolosis temperature of 280℃and peaked at 340 ℃. TGA analysis result of oil shale and bitumen showed that the temperature of bitumen pyrolosis was lower than the oil shale kerogen. The pyrolosis gas of Longkou oil shale could be used to in the production of LNG and LPG.
