| 20110049016 | BITUMEN UPGRADING USING SUPERCRITICAL FLUIDS - The invention provides systems and methods for extracting and upgrading heavy hydrocarbons from substrates such as oil sands, oil shales, and tar sands in a unitary operation. The substrate bearing the hydrocarbon is brought into contact with a supercritical or near-supercritical fluid, a source of hydrogen such as hydrogen gas, and a catalyst. The materials are mixed and heated under elevated pressure. As a consequence of the elevated temperature and pressure, upgraded hydrocarbon-containing material is provided in a single or unitary operation. In some embodiments, sonication can be used to improve the upgrading process. Fluids suitable for use in the process include carbon dioxide, hexane, and water. It has been observed that upgrading can occur within periods of time of a few hours. | 03-03-2011 |
| 20110000825 | CARBONACEOUS MATERIAL UPGRADING USING SUPERCRITICAL FLUIDS - Systems and methods for extracting, handling and upgrading carbonaceous material. The systems and methods involve forming a reaction mixture of a carbonaceous material, a supercritical fluid, a catalyst and a source of hydrogen, and maintaining the reaction mixture at moderate temperatures for modest time periods. Exemplary reaction temperatures are those below 200° C. Exemplary reaction times range from 30 minutes to less than 24 hours. | 01-06-2011 |
| 20100278708 | PROCEDURES FOR AMMONIA PRODUCTION - The invention provides systems and methods for producing ammonia under conditions having at least one of a temperature and a pressure that are respectively lower than the temperature and pressure at which the Haber process is performed. In some embodiments, a supercritical fluid is used as a reaction medium. | 11-04-2010 |
| 20090010836 | HYDROGEN STORAGE MATERIALS, METAL HYDRIDES AND COMPLEX HYDRIDES PREPARED USING LOW-BOILING-POINT SOLVENTS - The invention provides systems and methods for preparing hydrogen storage materials using low boiling point solvents or reaction media. Examples of such solvents or reaction media include dimethyl ether, ethyl methyl ether, epoxyethane, and trimethylamine. The synthesis of the hydrogen storage materials is conducted is a selected medium, and after synthesis is complete, the reaction medium is removed as necessary by moderate heating. | 01-08-2009 |
| 20080241056 | HYDROGENATION OF ALUMINUM USING A SUPERCRITICAL FLUID MEDIUM - An apparatus and a method for controllably converting aluminum into alane. In the system of the invention, a reaction between aluminum and hydrogen to form alane is performed at temperatures below 100° C. using a supercritical fluid such as CO | 10-02-2008 |
