Study on new processing technology of Fushun shale oil

Solvent refining of Fushun shale oil with furfural as solvent extraction agent is investigated.The results show that the raffinate yield decreases with the increasing of agent/oil mass ratio or reaction temperature,the extract yield increases under the same conditions,while the quality of raffinate oil is better.Heavy component from extract oil is used for blending different grades of asphalt such as heavy-traffic paving asphalt and building asphalt,light component from extract oil is used for the separation of non-hydrocarbon compounds,all kinds of light fuel oil are received through catalytic cracking experiment with the denitrified raffinate oil,the removed nitrogen compounds are also used for the separation of non-hydrocarbon compounds.
