20100324318 | ENRICHMENT OF MONOUNSATURATED ACIDS/ESTERS IN VEGETABLE OIL- OR ANIMAL FAT-BASED FEEDSTOCK USING METAL SALTS DISSOLVED IN IONIC LIQUIDS - In some embodiments, the present invention relates to an enrichment process that involves a separation and/or fractionation and/or enrichment of monounsaturated fatty acid/ester molecules from polyunsaturated fatty acid/ester molecules or, correspondingly, monounsaturated molecules from saturated molecules. Such processes are at least partially based on π(pi)-complexation between metal ions and unsaturated bonds of the extractible molecules (fatty acids/esters), wherein a greater degree of unsaturation provides for greater coordinating (bond) strength and corresponding selectivity in the associated π-complexation with metal ions. | 12-23-2010 |
20110203973 | PROCESS FOR UPGRADING HYDROCARBONS AND DEVICE FOR USE THEREIN - A process is disclosed using a dispersion of supercritical fluid and oil to upgrade a hydrocarbon feedstock such as a heavy oil into an upgraded hydrocarbon product or synthetic crude with highly desirable properties such as low sulfur content, low metals content, lower density (higher API), lower viscosity, lower residuum content, etc. The process utilizes a capillary mixer to form the dispersion. The process does not require external supply of hydrogen nor does it use externally supplied catalysts. | 08-25-2011 |
