| 20120184632 | SYNTHESIS GAS METHANATION PROCESS AND APPARATUS - In a synthesis gas methanation process, at least one first fraction of synthesis gas to treat is fed, together with steam, to a shift reactor where a shift reaction occurs; the gas flow produced in the shift reactor is then fed to a first methanation reactor where a methanation reaction occurs and then to further second methanation reactors in series, where further methanation reactions, performed with the addition of fresh synthesis gas which has not been subjected to the shift reaction. | 07-19-2012 |
| 20130090394 | PROCESS FOR PROVIDING HYDROGEN TO A SYNTHESIS GAS CONVERSION REACTION - A synthesis gas conversion process for carrying out the process is disclosed. A hydrogen-containing sweep gas is caused to flow across a water permselective membrane adjacent a synthesis gas conversion reaction zone in which synthesis gas is contacted with a catalyst and converted to effluent including water. Water is removed from the reaction zone through the membrane. The sweep gas has sufficient hydrogen partial pressure to cause hydrogen to pass through the membrane into the reaction zone. | 04-11-2013 |
| 20090054539 | PROCESS FOR THE PREPARATION OF DIMETHYL ETHER - Process for the preparation of dimethyl ether product by catalytic conversion of synthesis gas to dimethyl ether comprising contacting a stream of synthesis gas comprising carbon dioxide with one or more catalysts active in the formation of methanol and the dehydration of methanol to dimethyl ether to form a product mixture comprising the components dimethyl ether, methanol, carbon dioxide and unconverted synthesis gas, washing the product mixture comprising carbon dioxide and unconverted synthesis gas in a scrubbing zone with a liquid solvent being rich in potassium carbonate or amine and thereby selectively absorbing carbon dioxide in the liquid solvent, subjecting the thus treated product mixture to a distillation step to separate methanol and water from dimethyl ether and unconverted synthesis gas stream with a reduced content of carbon dioxide and separating the unconverted synthesis gas from the dimethyl ether product. | 02-26-2009 |
| 20090182064 | Reactive Separation To Upgrade Bioprocess Intermediates To Higher Value Liquid Fuels or Chemicals - The process and system of the embodiments utilize a reactive separation unit to upgrade a bioprocess intermediate stream to higher value liquid fuels or chemicals. The reactive separation unit simultaneously enables molecular weight and density increases, oxygen content reduction, efficient process energy integration, optional water separation for potential reuse, and incorporation of additional hydrocarbons or oxygenated hydrocarbons as co-feed(s). The use and selection of particular co-feed(s) for this purpose enables tailoring of the intended product composition. The process and system yields a product of higher alcohols, liquid hydrocarbons, or a combination of these. These can be split into two (or more) boiling point fractions by the same reactive separations unit operation resulting in product(s) that can be used as chemicals, chemical intermediates, or alternative (non-fossil-based) liquid transportation fuels. | 07-16-2009 |
| 20100267848 | METHOD AND REACTOR FOR THE PREPARATION OF METHANOL - Method and reactor for performing Fischer-Tropsch (FT) synthesis with controlled steam partial pressure by introducing cool points in the FT reactor, typically in form of cooled solid surfaces. At the surface, the low temperature will force condensation of the water into a liquid film. Thereby, the partial pressure of steam in the gas and reactor will not exceed significantly the vapour partial pressure at the liquid film and water from the gas stream will be removed as it is produced, i.e. steam induced deactivation is avoided. In addition, the decrease of hydrogen and carbon monoxide partial pressures due to dilution by steam will be kept low ensuring a constant high reaction rate. | 10-21-2010 |
| 20090048355 | PRODUCTION OF Cu/Zn/Al CATALYSTS VIA THE FORMATE ROUTE - The invention relates to a process for preparing Cu/Zn/Al catalysts. In this process, the metals are used in the form of their formates and are precipitated in a suitable form. Suitable precipitants are, for example, alkali metal carbonates. The invention further relates to a catalyst as can be obtained by the process according to the invention and to its use. | 02-19-2009 |
| 20090253815 | Process and Reactor for Implementing Exothermic and Endothermic Reactions - Implementing at least one endothermic and/or exothermic reaction in a compact reactor which has passages for conducting gaseous and/or liquid media, through which passages the reactants of the endothermic or exothermic reaction as well as a heating medium or coolant are sent, whereby
