Oil Shale can be directly burned as boiler fuel to generate steam for power generation,and can also be decomposed through pyrolysis to generate shale oil,shale semi coke,and dry distillation gas similar to natural gas.It is an important supplementary energy source for petroleum,with broad development prospects and significant strategic significance for changing the world's energy structure.Sort out the characteristics,processing and utilization technologies,and current development and utilization status of oil shale resources in major oil shale countries around the world.Various countries around the world are constantly innovating and improving their exploration,extraction,and distillation technologies for oil shale.Many countries,including Estonia,Brazil,and the United States,have already developed advanced oil shale processing technologies for rational extraction and industrial utilization of oil shale.China is currently processing and utilizing oil shale in cities such as Fushun,Xinjiang,and Gansu,with Fushun having the largest annual shale oil production.The overall level of development and utilization of oil shale in China is relatively low,and the development and utilization of new technologies are not mature enough.A complete industrial chain based on oil shale has not yet been formed.In the future,more relevant national policy support is needed,further increasing scientific research investment in oil shale,researching and developing new technologies that adapt to China's characteristics,continuously improving the industrial and resource utilization level of oil shale,and increasing processing capacity Reduce ecological pollution while increasing oil production,and adhere to the path of new industrialization.
