摘　　要：孤岛减压渣油经加氢裂化后的尾油 ,化学组成和性质发生了很大变化 ,接近石蜡基的大庆减压渣油 ;色谱模拟脱沥青研究表明 ,在很高的脱沥青油收率下 ,脱沥青油的残炭值、氮含量仍保持较低水平 ,脱蜡油性能优越 。After Gudao vacuum residue has been processed by hydrocracking,the chemical composition and properties of the hydrogenated residue have changed greatly and are approximate to Daqing vacuum residue of paraffinic.Deasphalting research by simulated chromatography indicated that carbon residue and nitrogen content of deasphalting oil remain low under high yield of deasphalting oil,with superior performances for dewaxing oil.It is shown that Gudao VRDS residue could be used as feedstock to produce the heavy viscosity lubricating base oils.
