20140255295 | Process for the Manufacture of Hydrogen Peroxide - A continuous process for producing hydrogen peroxide by an anthraquinone process, comprising the steps of: (i) hydrogenating an organic working solution containing one or more anthraquinone derivatives in the presence of a heterogeneous catalyst to form a hydrogenated working solution; (ii) oxidizing the hydrogenated working solution by introducing an oxygen-containing oxidizing gas at an overpressure into an oxidation reactor, and contacting the oxidizing gas with the hydrogenated working solution to form an oxidized working solution, whereby hydrogen peroxide is formed; (iii) withdrawing an oxidation off gas from the oxidation reactor; (iv) recovering the formed hydrogen peroxide from the oxidized working solution; (v) subjecting the oxidation off gas withdrawn from said oxidation reactor, which has an excess pressure over atmospheric pressure, to a demisting treatment to obtain a demisted oxidation off gas; and (vi) feeding the demisted oxidation off gas as propellant gas into a gas ejector to produce a vacuum. | 09-11-2014 |

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 |
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 |
