| 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 |
| 20100078354 | 170 NEUTRAL BASE OIL WITH IMPROVED PROPERTIES - 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° C., a VI from 105 to less than 120, and a Noack volatility from 6.6 to 11.5 wt % or a CCS VIS at −25° C. from 2500 to 4500 mPa·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° C., and other properties. | 04-01-2010 |
| 20100078355 | PROCESS TO MANUFACTURE A BASE STOCK AND A BASE OIL MANUFACTURING PLANT - 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 −25° 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. | 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 |
| 20100219100 | BASE OIL SLATE PREPARED FROM A WAXY FEED - A base oil slate comprising three or more base oil grades having kinematic viscosities at 100° C. between about 1.8 cSt and about 30 cSt prepared from a waxy feed wherein each of the base oil grades is a base oil blend which comprises: (a) between about 0.1 wt. % and about 99.9 wt. % of a distillation fraction prepared in light block mode operation; and (b) between about 0.1 wt. % and about 99.9 wt. % of a distillation fraction prepared in medium block mode operation. Also, a base oil slate prepared from a waxy feed, said product slate comprising 3 or more base oil grades, each base oil grade having a kinematic viscosity at 100° C. between about 1.8 cSt and about 30 cSt and a VI greater than an amount defined by the equation VI=Ln(Vis100, in cSt)+95, wherein Ln(Vis100, in cSt) is the natural log of the kinematic viscosity at 100° C. | 09-02-2010 |
| 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 |
