Model Test Study of Underground Co-Gasification of Coal and Oil Shale

Abstract:

For testing the feasibility of in-situ exploring oil shale by underground coal gasification. Based on the specification analysis of coal and oil shale, through simulating the occurrence state and characteristics of coal and oil shale, the underground Co-gasification model test was carried-out. In different gasification conditions (φ(O2) are 30%、35%、40%、45%、50% and oxygen/steam) ,The temperature-field extend rules of coal and oil shale、the separate-out rules of oil shale production and influence of oil shale on the quality of gas were studied. The results show that: when φ(O2) is 40-45%, temperature-rising rate is 7°C/min、extend rate of gasification face is 0.036m/h, the extend of temperature field is continuous and stable, the temperature change of oil shale and coal are synchronously , the high temperature of oil shale can up to 1000 °C above, that can satisfied the requirement of oil-gas collecting; and the same time , The heat-value of syngas improved 26.37%; The technological parameter was obtained in this test.
