HAZY-FREE AT 0°C HEAVY BASE OIL AND A PROCESS FOR PRODUCING

摘要

A process for producing a base oil composition from a deasphalted oil (DAO) feed, where the DAO feed undergoes hydrotreating, hydrocracking, catalytically dewaxing, hydrofinishing, and fractionating to generate the base oil composition. The base oil composition includes a hazy-free at 0° C. heavy base oil comprising (a) a kinetic viscosity ranging from 15 to 21 cSt at 100° C., (b) a 5 viscosity index of at least 95, (c) a pour point of less than −12° C., (d) a cloud point of less than −18° C., and (e) a total aromatics content of 2 wt % or less, where the hazy-free at 0° C. heavy base oil maintains a hazy-free appearance when stored undisturbed at 0° C. during a test period.
