Deasphalted oil (DAO)%high-quality bright stock%white oil%hydrogenation
Using a three-stage hydrogenation process, high-quality 150 bright stock (150BS) was produced from light DAO (LDAO, light deasphalted oil), which was obtained from vacuum residue of heavy naphthenic crude oil of Zone No.9 in Xinjiang. The 150BS product, whose viscosity index is greater than 90, is colorless and has good viscositytemperature characteristics. This product turns out to be an excellent blending component of high-grade engine oil. And with the 150BS as a feed, very high-viscosity white oil was also produced by a further hydrofining step to substantially reduce the amount ofpolyaromatics contained in the feed.
