Title:
METHOD FOR PREPARING LUBRICATING BASE OILS BY USING VACUUM DISTILLED DEASPHALTED OIL
Document Type and Number:
WIPO Patent Application WO/2011/152680
Kind Code:
A2
Abstract:
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 to obtain heavy deasphalted oil (H-DAO) and light deasphalted oil (Lt-DAO), and treating the H-DAO by catalytic reaction and the Lt-DAO by hydrogenation, respectively. According to the present invention, it is possible to obtain a heavy lubricating base oil (150BS) of a high viscosity grade which could not obtained by a known catalytic reaction and a lubricating base oil of group III by hydrogenation, at a high yield, and thus economical efficiency and efficiency are excellent.
