为寻求大庆减压渣油转化的有效方法 ,利用“超临界流体萃取分离”技术 ,在实验室对大庆减压渣油 /催化裂化油浆混合原料进行分离 ,并对分离得到的脱油沥青和脱沥青油进行了评价。结果表明 ,掺兑 10 %～ 30 %油浆的混合原料 ,其脱油沥青可生产优质道路沥青产品 ;掺兑 10 %～ 2 0 %油浆的混合原料 ,其脱沥青油的催化裂化反应性能明显优于大庆减压渣油 In order to find an effective method for the conversion of Daqing vacuum residue, the “Daqing vacuum residue / FCC slurry mixing material” was separated in the laboratory by “supercritical fluid extraction and separation” technology. The separation of deoiled asphalt and Deasphalted oil was evaluated. The results show that the blended asphalt mixture with 10% ~ 30% oil slurry can produce high quality road asphalt products with deoiled asphalt. The catalytic cracking reactivity of deasphalted oil mixed with 10% ~ 20% oil slurry Obviously superior to Daqing vacuum residue
