| 20110184201 | METHODS AND COMPOSITIONS FOR REFINING LIPID FEED STOCKS - The present invention relates to systems and methods of using fatty acid alkyl ester solutions to refine feed stocks before converting the feed stocks into fatty acid fatty acid alkyl esters. In an embodiment, the invention includes a method for producing fatty acid alkyl esters. The method can include mixing a crude lipid feed stock with a refining solution to form a crude product mixture, the refining solution comprising greater than about 10 wt. % fatty acid alkyl esters. The method can include extracting the liquid phase from the crude product mixture to obtain a purified lipid feed stock. The method can also include reacting the purified lipid feed stock with an alcohol to form a product mixture comprising fatty acid alkyl esters. In an embodiment, the invention includes a method of making a fatty acid alkyl ester composition. The method can include extracting lipids from a corn-based ethanol production byproduct, adding an alcohol solution to the lipids to form a reaction mixture, and contacting the reaction mixture with a metal oxide catalyst. Other embodiments are included herein. | 07-28-2011 |
| 20110060153 | SYSTEMS AND METHODS FOR REFINING ALKYL ESTER COMPOSITIONS - The present invention relates to systems and methods for producing and/or refining alkyl ester compositions. In an embodiment the invention includes a method of producing a refined fatty acid alkyl ester composition. The method can include contacting a fatty acid feedstock and an alcohol with a first metal oxide catalyst at a temperature of greater than 200 degrees Celsius and a pressure of greater than 500 psi to form an unrefined fatty acid alkyl ester composition. The method can further include combining the unrefined fatty acid alkyl ester composition with dimethyl carbonate to form a refining mixture. The method can also include contacting the refining mixture with a second metal oxide catalyst at a temperature of greater than 100 degrees Celsius to form a refined fatty acid alkyl ester composition. Other embodiments are also described herein. | 03-10-2011 |
