20090221725Production of ethanol from methanol - A process for converting methanol to ethanol which comprises reacting methanol and carbon monoxide in the presence of a catalyst to produce a product comprising at least 25 mole % methyl acetate and, in some instances, acetic acid. The acetic acid then is reacted with at least one alcohol to produce at least one acetate selected from methyl acetate, ethyl acetate, and butyl acetate. The at least one acetate (if produced) and the methyl acetate produced as a result of reacting methanol and carbon monoxide then are hydrogenated to produce ethanol. Syngas may be produced from biomass to produce all or a portion of the methanol, hydrogen, and carbon monoxide requirements for the process.09-03-2009
20100022671PRODUCING METHANOL AND ITS PRODUCTS EXCLUSIVELY FROM GEOTHERMAL SOURCES AND THEIR ENERGY - The invention provides a method for producing methanol and its products exclusively from a geothermal source as the sole source material also using the needed energy from the geothermal energy source. The method includes separating or isolating carbon dioxide accompanying hot water or steam of the source, generating hydrogen from the water and subsequently preparing methanol from the carbon dioxide and hydrogen. The methanol can be further converted into dimethyl ether or other products.01-28-2010
20090326080Production of ethanol from methanol - A process for converting methanol to ethanol which comprises reacting methanol and carbon monoxide in the presence of a catalyst to produce a product comprising at least 25 mole % methyl acetate and, in some instances, acetic acid. The acetic acid then is reacted with at least one alcohol to produce at least one acetate selected from methyl acetate, ethyl acetate, and butyl acetate. The at least one acetate (if produced) and the methyl acetate produced as a result of reacting methanol and carbon monoxide then are hydrogenated to produce ethanol. Syngas may be produced from biomass to produce all or a portion of the methanol, hydrogen, and carbon monoxide requirements for the process.12-31-2009
20100317751PROCESS FOR THE EXTRACTION OF HYDROGEN FROM A GAS MIXTURE - The invention relates to a process for the extraction of hydrogen from a gas mixture comprising hydrogen and carbon monoxide and optionally nitrogen, carbon dioxide, lower hydrocarbons and/or water, by contacting the gas mixture with a non-porous polyimide-based membrane, especially with the selective side of an asymmetric membrane, to obtain a hydrogen rich permeate and a hydrogen lean retentate, the polyimide-based membrane being a specific mixture of two polyimides. This specific membrane shows a very high hydrogen/carbon monoxide selectivity. The invention is especially suitable for the upgrading of synthesis gas obtained by partial oxidation and/or reforming of hydrocarbonaceous feedstream for use in hydrocarbon synthesis reaction as the Fischer-Tropsch reaction.12-16-2010

20090149558METHODS AND APPARATUS FOR CONTINUOUS REMOVAL OF CARBON DIOXIDE FROM A MIXTURE OF REACTING GASES - The disclosed invention provides methods and apparatus for producing one or more C06-11-2009
20110269854PROCESS FOR THE PRODUCTION OF METHANOL INCLUDING ONE OR MORE MEMBRANE SEPARATION TYPES - Disclosed herein is a methanol production process that includes a membrane separation step or steps. Using the process of the invention, the efficiency of methanol production from syngas is increased by reducing the compression requirements of the process and/or improving the methanol product yield. As an additional advantage, the membrane separation step generates a hydrogen-rich stream which can be sent for other uses. An additional benefit is that the process of the invention may debottleneck existing methanol plants if more syngas or carbon dioxide is available, allowing for feed of imported carbon dioxide into the synthesis loop. This is a way of sequestering carbon dioxide.11-03-2011
518724000 SOLVENT EXTRACTION UTILIZED 1
20090156698PROCESS FOR THE PREPARATION OF PURE DIMETHYL ETHER - Process for the preparation of dimethyl ether product by catalytic conversion of synthesis gas to dimethyl ether comprising the steps of contacting a stream of synthesis gas comprising carbon dioxide in a dimethyl ether synthesis step in one or more reactors and with one or more catalysts being active in formation of methanol and dehydration of methanol to dimethyl ether, to form a product mixture comprising the dimethyl ether and carbon dioxide, washing the product mixture in a scrubbing zone with a liquid solvent being rich in dialkyl ether of a polyalkylene glycol and thereby dissolving carbon dioxide and dimethyl ether in the liquid solvent, treating the liquid solvent being withdrawn from the scrubbing zone sequentially in separation zone to effect desorption of the dissolved carbon dioxide and to recover a substantially pure dimethyl ether product and the liquid solvent in its substantially lean form and recycling the lean liquid solvent to the scrubbing zone.06-18-2009
