| 20130313160 | Isolating Lubricating Oils from Subsurface Shale Formations - Disclosed herein are methods for isolating heavy saturated hydrocarbons from a subsurface shale formation comprising kerogen and an extractible organics component. These methods can be used to provide a bright stock product. The process comprises extracting an extractible organics component from subsurface shale formations comprising kerogen and the extractible organics component in an inorganic matrix and isolating a heavy hydrocarbon fraction comprising saturated beta-carotene. The methods utilize a hydrocarbon solvent to at least partially solubilize the extractible organics component. Among other factors, these processes are based on the discovery that the extractible organics is composed of a heavy hydrocarbon component containing saturated beta-carotene. The saturated beta-carotene product is a valuable commercial product. The presently disclosed processes are more environmentally benign, more economical, and more efficient in producing commercial products and in providing access to kerogen. | 11-28-2013 |

| 20160145512 | PRODUCTION OF LUBRICANT BASE STOCKS WITH CONTROLLED AROMATIC CONTENTS - Methods are provided for producing Group II and Group III base stocks with a controlled or consistent aromatics content. An aromatics-rich base stock, such as a Group I base stock or an alkylated aromatic base stock, can be added to the catalytically treated base stock in a minimal amount after the final catalytic treatment step but prior to fractionation. At the beginning of a processing run for forming lubricant base stock products, about 0.25 wt % to about 1.25 wt % of the Group I base stock can be added to a catalytically processed feed after the final catalytic processing stage but prior to fractionation to form the Group II and/or Group III base stock. During the course of the processing run, the amount of Group I base stock added can be reduced roughly in correspondence with the increase in aromatics caused by catalyst deactivation. This can allow a catalytically processed lubricant base stock product to be generated that contains at least about a threshold (minimum) aromatics content during the course of a processing run. Alternatively, this can allow a catalytically processed lubricant base stock product to be generated that has consistent aromatics content during the course of the processing run. | 05-26-2016 |
