Abstract A systematical method for selective separation of nitrogen compounds from the extracted oil of the Fushun shale oil has been developed. The results show that improving the solvent��oil ratio��raising the temperature, extending the extraction time or the settling time,the removal rate can be increased. Under the condition, the solvent��oil ratio is 1.0��the temperature of reaction is 60 �棬the extraction time is 40 min and the settling time is 2.5 h, the removal ratio of basic nitrogen compounds can be as high as 97.5%, and the removal ratio of total nitrogen compounds can be as high as 40%. The equipments of the method is simple and the cost is low.
