We provide a process to manufacture a base stock, comprising hydrocracking, separating, and dewaxing, wherein the base stock has a ratio of Noack volatility to CCS VIS at &#x2212;25&#xb0; C. multiplied by 100 from 0.15 to 0.40. We also provide a base stock made by a process, and a base oil manufacturing plant that produces the base stock.

Process to manufacture a base stock

Base oil manufacturing plant

We provide a base stock comprising hydrocarbons with consecutive numbers of carbon atoms, wherein the base stock has a boiling range from 388 to 538&#xb0; C., a VI from 105 to less than 130, and a Noack volatility from 5 to 11.5 wt % or a CCS VIS at &#x2212;25&#xb0; C. from 2000 to 4000 mPa&#xb7;s. We also provide a base stock slate comprising the base stock and an additional base stock having an additional boiling range from 371 to 496&#xb0; C., and other properties.

Process to manufacture a base stock and a base oil manufacturing plant

We provide a base oil comprising hydrocarbons with consecutive numbers of carbon atoms. The base oil has a boiling range from 700 to 925&#xb0; F. (371 to 496&#xb0; C.), a VI from 105 to 119, and either a Noack volatility less than 18 wt % or a CCS VIS at &#x2212;25&#xb0; C. less than 1500 mPa&#xb7;s. The base oil may have a ratio of Noack Volatility to CCS VIS at &#x2212;25&#xb0; C. multiplied by 100 from 0.80 to 1.55.
