20090321308 | METHOD FOR PRODUCING A BASE OIL HAVING HIGH WEIGHT PERCENT TOTAL MOLECULES WITH CYCLOPARAFFINIC FUNCTIONALITY AND LOW WEIGHT PERCENT MOLECULES WITH MULTICYCLOPARAFFINIC FUNCTIONALITY - 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 | 12-31-2009 |
20100077842 | METHOD FOR PREDICTING A PROPERTY OF A BASE OIL - A method for predicting a property of a base oil, and a blend chart, are provided. The method for predicting a property of a base oil includes selecting two base stocks, and preparing a chart having the viscometric property under low temperature and the volatility of both base stocks and curves between them that is used to predict whether blends of two base stocks will meet requirements for a finished lubricant. | 04-01-2010 |
20100078353 | PROCESS TO MAKE A 110 NEUTRAL BASE OIL WITH IMPROVED PROPERTIES - A process to manufacture a base oil, comprising selecting an original base oil having an original VI, an original volatility, and an original CCS VIS; and removing a lower boiling fraction, whereby the base oil is made having a kinematic viscosity at 100° C. from 4.2 to 4.6 mm | 04-01-2010 |
20100081590 | 110 NEUTRAL BASE OIL WITH IMPROVED PROPERTIES - We provide a base oil comprising hydrocarbons with consecutive numbers of carbon atoms. The base oil has a boiling range from 700 to 925° F. (371 to 496° C.), a VI from 105 to 119, and either a Noack volatility less than 18 wt % or a CCS VIS at −25° C. less than 1500 mPa·s. The base oil may have a ratio of Noack Volatility to CCS VIS at −25° C. multiplied by 100 from 0.80 to 1.55. | 04-01-2010 |
20100105591 | FINISHED LUBRICANT WITH IMPROVED RUST INHIBITION MADE USING FISCHER-TROPSCH BASE OIL - There is provided a finished lubricant, comprising:
| 04-29-2010 |
20100219101 | PROCESS TO MAKE A LIGHT BASE OIL FRACTION HAVING LOW NOACK VOLATILITY - A process to make a light base oil fraction having a wt % Noack volatility between 0 and 100 and additionally less than a Noack Volatility Factor (NVF), wherein the Noack Volatility Factor is defined by the equation: 900×(Kinematic Viscosity at 100° C.) | 09-02-2010 |
20100279904 | ELECTRICAL INSULATING OIL COMPOSITIONS AND PREPARATION THEREOF - An electrical insulating oil composition comprising a heavy reformate as an anti-gassing agent is provided with excellent gassing tendency. In one embodiment, the composition displays a gassing performance of <30 μL per minute as measured according to ASTM D2300-08. In a second embodiment, the composition displays a gassing performance of <0 μL per minute. | 11-04-2010 |
