Method for upgrading olefinic lubes |
| abstract |
The viscosity index of synthetic lubricant stocks such as those produced by olefin oligomerization is increased by contacting such stocks with a solid acidic isomerization catalyst such as boron trifluoride at elevated temperatures, say above about 200° C. The high viscosity index fractions of the resulting product may be sorbed by a shape-selective zeolite such as ZSM-5 and recovered to produce a high VI lubricant. |
