摘要： A method of manufacturing high-quality naphthenic base oils comprising a high aromatic content and a large amount of impurities with a boiling point higher than that of gasoline. High-quality naphthenic base oil may be manufactured from light cycle oil (LCO) and slurry oil (SLO), which are inexpensive, and have a high aromatic content, a large amount of impurities, and which are effluents of a fluidized catalytic cracking (FCC) unit. The method also relates to the pretreatment process of a feedstock, where the amounts of impurities (sulfur, nitrogen, polynuclear aromatic compounds and various metals components) in the feedstock are reduced.

摘要： Disclosed is a method of simultaneously manufacturing high quality naphthenic base oil and heavy base oil using a single catalyst system, by subjecting an oil fraction (slurry oil or light cycle oil) produced by fluid catalytic cracking and an oil fraction (deasphalted oil) produced by solvent deasphalting to hydrotreating, catalytic dewaxing and hydrofinishing of the single catalyst system, thereby obtaining not only products having low viscosity but also heavy base oil products (150BS) having high viscosity which was impossible to obtain using a conventional catalytic reaction process, and also thereby producing base oil products having different properties using the single catalyst system, thus generating economic benefits and exhibiting superior efficiency.
