摘　　要：采用短程分子蒸馏技术,对沙轻减压渣油进行深拔分离,并对各窄馏分进行性质分析,及考察其催化裂化性能。结果表明,沙轻减压渣油深拔温度不宜过高,应在600℃之内。各窄馏分油具有较好的催化裂化性能,可直接进行催化裂化。并得出反应产品分布与原料性质及特性因数之间的关系。该项研究为沙轻减压渣油的深加工提供有利的实验依据。The Saudi-Arabian light vacuum residue was cut using short-distance molecular als-tillation. The property of each narrow range cut was analyzed and the catalytic cracking of each cut wastested. The results indicated that the optimum cutting temperature was lower than 600℃. These narrowrange cuts had good crackability and could be used as FCC feedstock. The correlation equation for prod-uct distribution versus feedstock property and K factor was deduced. The research provides experimentalbasis for deep processing of the said residue.
