摘　　要：对加拿大油砂稀释原油进行了常减压蒸馏-溶剂(正戊烷)脱沥青-调和改质加工工艺优化研究。结果表明:萃取温度180℃、剂油比(溶剂与减压渣油的体积比)8∶1、萃取压力4.4 MPa为较优的脱沥青萃取工艺条件;在上述较优条件下制备的脱沥青油与常、减压馏分油按比例调和,并掺加体积分数为16.5%的稀释剂(石脑油)所制得的合成油,不仅满足加拿大管输油的标准要求,还降低稀释剂掺量的45%~52%;而且,所得脱油沥青能够有效改善基质沥青的高温性能,可作为性能优异的硬质沥青改质添加组分。The optimization of the atmospheric and vacuum distillation-solvent(n-pentane)deasphalting-blending modification process was carried out on the diluted crude oil from Canadian oil sands.The results showed that the optimal extraction conditions were extraction temperature at 180℃,solvent to oil ratio(volume ratio of solvent to vacuum residue)at 8∶1 and extraction pressure at 4.4 MPa.The synthetic oil was prepared by blending the deasphalted oil produced under above optimal conditions with the atmospheric and vacuum fractions in proportion,and adding the diluent(naphtha)with the volume fraction of 16.5%,which could not only meet the requirements of Canadian pipeline oil transportation standards,but also reduced the diluent dosage by 45%-52%.Moreover,the obtained deoiled asphalt could effectively improve the high-temperature performance of the base asphalt,and be used as an additive component to upgrade hard asphalt with excellent performance.
