A method for producing a base oil having a high ratio of weight percent molecules with monocycloparaffinic functionality to weight percent molecules with multicycloparaffinic functionality by hydroisomerization dewaxing a selected Fischer-Tropsch wax under hydroisomerization conditions including a hydrogen to feed ratio from about 712.4 to about 3562 liter H/liter oil.

Method for producing a base oil having high weight percent total molecules with cycloparaffinic functionality and low weight percent molecules with multicycloparaffinic functionality

A lubricating base oil manufacturing plant comprising a means for hydroisomerization dewaxing a wax at a specified hydrogen to feed ratio and a means for hydrofinishing the hydroisomerized wax to produce one or more base oils having greater than 10 weight percent total molecules with cycloparaffinic functionality and less than 0.5 weight percent molecules with multicycloparaffinic functionality.

Lubricating base oil manufacturing plant for producing base oils having desired cycloparafinic functionality

A lubricant base oil blend having a wt % Noack volatility less than 29, comprising a) a light base oil fraction having a kinematic viscosity at 100&#xb0; C. between 1.5 and 3.6, and a wt % Noack volatility both between 0 and 100 and less than a Noack Volatility Factor, and b) a petroleum-derived base oil fraction. A process to make the lubricant base oil blend having a wt % Noack volatility less than 29. Also, a pour point depressed lubricant base oil blend having a Brookfield viscosity at &#x2212;40&#xb0; C. of less than 18,000 cP, comprising the light base oil fraction, a petroleum-derived base oil fraction, and a pour point depressant.

Lubricant base oil blend having low wt% noack volatility

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.
