Abstract Carbonium ion can be generated easier when low-carbon alcohols are added to hydrocracking tail oil, which initiate the cracking reaction of macromolecular n-paraffin. So the yield of lube oil base oil increases, while that of paraffin decreases, but the total yield of the two products increases. When the low-carbon alcohol is added to the raw oil for non-hydrodewaxing reaction of hydrocracking tail oil, the pour point of lubricating oil base oil declines, the flash point and the viscosity increases slightly, and the distillation range of paraffin declines slightly, but the properties of products changes little, so they can meet the actual production requirements of the factory. By examining the influence of low-carbon alcohol on the yield and properties of lubricating oil base oil and paraffin, tert-butyl alcohol is an ideal chain initiator, and the most suitable addition is 1.0 w%.

低碳醇对加氢裂化尾油非加氢脱蜡反应影响的研究

摘要 在加氢裂化尾油中加入低碳醇，更容易生成碳正离子，引发大分子正链烷烃的裂化反应。因此润滑油基础油的收率增加，而石蜡的收率降低，但两种产品的总收率增加。加氢裂化尾油非加氢脱蜡反应原料油中加入低碳醇后，润滑油基础油倾点下降，闪点和粘度略有增加，石蜡的馏程略有下降，但产品的性能变化不大，可以满足工厂的实际生产要求。通过考察低碳醇对润滑油基础油和石蜡收率和性能的影响，
