摘要
考察了溶剂脱沥青方法对催化裂化油浆的分离效果，结果表明，油装可以得到选择性分离，得到的脱沥青油以饱和分为主，其性质与假化裂化新鲜料性质相当，脱抽沥青以多环芳烃为主，该多环芳烃的氢含量、芳碳率已与减压渣油中正庚烷沥青质相近。
Solvent deasphalting of FCC slurry was studied. The result showed that the selective separation of the slurry can be realized. The deasphalted oil so obtained was mostly composed of saturates which properties were comparable with FCC fresh feed. The separated asphalt was rich in polynuclear aromatics which hydrogen content and fa were close to those of asphaltenes (heptane insolubles) in vacuum residues.
