METHOD FOR PREPARING LUBRICATING BASE OILS BY USING VACUUM DISTILLED DEASPHALTED OIL |
摘要 |
The present invention relates to a method for preparing lubricating base oils by using vacuum distilled deasphalted oil, and more specifically, to a method for preparing various kinds of lubricating base oils by distilling a distillate obtained from a solvent deasphalting (SDA) process under reduced pressure to obtain heavy deasphalted oil (H-DAO) and light deasphalted (Lt-DAO) and then treating the H-DAO and the Lt-DAO by catalytic reactions, respectively. According to the present invention, it is possible to obtain heavy lubricating base oil (150BS) of a high viscosity grade which can not be obtained by a known catalytic reaction and a lubricating base oil of group III by hydrogenation, in a high yield, and thus economical efficiency is excellent. |
