摘　　要：为了研究油页岩脱蜡后其干馏产物的变化特性,对山东龙口油页岩进行蜡的脱除,对脱蜡后的页岩样品进行干馏试验,测定干馏产物的分布.利用扫描电子显微镜进行固体颗粒表面微观特性试验,利用比表面积分析仪分析脱蜡后页岩微观孔隙特性的变化.进行了页岩油的品质分析,研究脱蜡对油品的影响。试验结果表明:预脱蜡后油页岩的含油率变化较小,发热量略有下降;孔的结构特性受脱蜡的影响较大,总比表面积减小,孔容和孔径均有不同程度的增大,且微孔减少,大孔增加;脱蜡后页岩干馏制取的页岩油有机质含量减少,其密度、粘度、凝点和倾点均显著降低,而发热量略有增加.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.
