Abstract: In order to realize the value increment of light furfural extract oil, the technical feasibility of preparation of crude white oil by hydrogenation process using naphthenic light furfural extraction oil as blending feedstock was studied in pilot plant. The results indicated that the qualified crude white oil product can be prepared by adjusting the blending ratio and optimizing the process conditions of hydrogenation unit, while the unit can run smoothly using the light furfural extract oil as blending feedstock

Key words: furfural refining, extract oil, hydrotreating, blending, crude white oil
