This article mainly in Longkou Shandong oil shale as the research object.By the method of extraction of Montan wax before retorting of oil shale wax,and put the shale which is after extraction into an environment that initial temperature is 20℃ and the final temperature is 520℃,keeping an heating rate of 10℃/min,and let the shale in the final temperature 30 minutes,doing experimental study on oil shale retorting.To mention after wax oil shale and oil shale original lu zhen experiment analysis,BET specific surface area and SEM,shale oil color qualitative analysis.Research results showed that extraction of shale wax before retorting of shale oil makes the hole of oil shale improved,pore volume and the aperture are increased in a different degree.It is conducive to exporting when retort the oil shale,extracting the wax on oil shale have a good influence on the quality of oil shale.The extracting of shale wax have little influence on the oil containing of the oil shale.And the oil containing of the oil shale with dimethylbenzene solvent extraction is more than that is not extracting,in this way,the quality of the oil shale will improve.
