摘　　要：利用糠醛、N-甲基吡咯烷酮(NMP)、二甲基亚砜(DMSO)等极性溶剂,正戊烷、正庚烷、石油醚等非极性溶剂对新疆混合原油减三线馏分进行萃取、反萃取,结合Al2O3色谱柱吸附、洗柱等方法,从副产物中生产出主要质量指标合格的高芳烃橡胶油和环保型橡胶油。高芳烃橡胶油芳烃质量分数达80%以上,环保型橡胶油多环芳烃(PCA)质量分数在3%以下。剩余原料的杂质含量降低、碳型分布合理、黏度指数提高,比较适合做润滑油原料。做为催化裂化原料时轻质油收率提高2.9%、焦炭产率下降1.3%。In repeated extraction and reverse extraction of Xinjiang commingled crude oil on third vac-uum side straight-run distillation cut with polar solvents like furfural,NMP and DMSO and non-polar sol-vents like n-pentane,n-heptane and petroleum ether,with the help of Al2 O3 chromatographic column ad-sorption and wash column,qualified high aromatic rubber oil and environmental protection rubber oil can be produced from the by-products.The quality volume of high aromatic rubber aromatic oil can be reached o-ver 80% and polyaromatic hydrocarbon PCA is under 3%.Surplus stock is suited to be crude lube stock with less impurity,reasonable carbon distribution and high viscosity index,which increases the light oil yield by 2.9% and reduces the coke yield by 1.3% as catalytic cracking material.
