摘要： 为合理利用青岛炼化的焦化蜡油, 开展了糠醛抽提 - 催化裂化组合工艺的实验室研究。糠醛抽提试验 结果表明, 抽提最佳条件: 温度为6 0℃, 剂油质量比为2, 得到抽余油的收率为5 2. 5 5%, 抽余油中饱和分质量分数为 6 0. 8 3%, 芳烃和胶质的含量降低, 性质得到明显的改善。催化裂化性能评价表明, 焦化蜡油由于含有大量难裂化的 稠环芳烃组分以及较高的氮化物, 导致转化率低, 产物分布差。与焦化蜡油相比, 抽余油催化裂化的转化率明显提 高, 产品分布得到了明显的改善, 可作为催化裂化的原料进行掺炼。

Abstract: In order to process appropriately the coking gas oil from Qingdao Petrochemical Co., a laboratory investigation of integrated processing of furfural extractioncatalytic cracking was carried out. The optimal extraction parameters of the furfural extraction were determined, in which the temperature was 60 ℃, and the solventtooil ratio was 2. The raffinate yield was 52.55% by weight of the coking gas oil, in which the saturates content was 60.83%. Also the aromatics and resins contents were reduced, resulting in the properties improvement of the raffinate. The results of catalytic cracking evaluation for coking gas oil indicated that it had low conversion rate and bad product distribution due to the high percent of hard cracking component of polycyclic aromatic hydrocarbons and nitrides. Compared with the coking gas oil, the conversion rate of raffinate products distribution had been significantly improved. And the raffinate can be blended in the feedstock for catalytic cracking.
