Oil shale, as an important alternative energy for the conventional oil resources, have been attracted renewed attention due to the uncertainty in the long-term on the availability of the crude oil supplies and the world energy crisis. Oil shale is consisted of 20-30 wt. % organic matter and 70-80wt% inorganic mineral. Kerogen, the main organic matter in the oil shale, can be converted to shale oil, semi-coke, water and pyrolysis gas through pyrolysis. So the research on pyrolysis of oil shale will favor the understanding the development of energy thermal conversion process.
