| 20090282739 | PROCESS FOR THE PREPARATION OF SYNTHESIS GAS FROM BLACK LIQUOR - A process for the adjustment of the composition of a synthesis gas produced in a high temperature black liquor gasifier. The process includes the steps of (a) generating a gasifier effluent stream from black liquor in the gasifier by a blast and optionally an atomising stream; (b) optionally quenching the gasifier effluent stream with a gas stream to form a gas quenched effluent stream; (c) quenching the gasifier effluent of step (a) or the gas quenched effluent gas stream of step (b) with a water stream to form a raw synthesis gas; (d) further cooling and cleaning and separating the raw synthesis gas to form a purified unprocessed synthesis gas with an appropriate H | 11-19-2009 |
| 20100036186 | PROCESS FOR THE SYNTHESIS OF HYDROCARBON CONSTITUENTS OF GASOLINE - Process for the synthesis of hydrocarbon constituents of gasoline comprising catalytic conversion in a gasoline synthesis step of an oxygenate-containing feed comprising methanol and/or dimethyl ether and a mixture of at least on a total oxygenate basis 0.05 wt % C | 02-11-2010 |
| 20100130775 | PROCESS FOR THE CONVERSION OF ETHANOL TO ACETIC ACID - Process for the preparation of acetic acid comprising the steps of: providing a feed stream of water and ethanol; adding the feed stream to a recycle stream comprising unconverted ethanol and water; heating the admixture to a predetermined reaction temperature and passing the thus heated admixture over a catalyst being active in non-oxidative conversion of ethanol to acetic acid to obtain an effluent being rich in acetic acid; optionally cooling the effluent; separating the effluent into a stream rich in acetic acid being essentially free of water, a hydrogen containing stream, and a stream with unconverted amounts of ethanol, water and reactive derivates of acetic acid and optionally ethyl acetate; recycling the stream with unconverted amounts of ethanol and water to step (a); determining the amount of water in the recycle stream and adjusting the composition of the ethanol and water feed stream in step (a) to a water/ethanol mole ratio of between 0.3/0.7 to 0.6/0.4. | 05-27-2010 |
| 20100130776 | PROCESS AND REACTOR FOR THE THERMONEUTRAL CONVERSION OF ETHANOL TO ACETIC ACID - A process and reactor for the production of acetic acid comprising the steps of: passing a feed stream containing ethanol and water together with a predetermined feed rate of an oxygen containing atmosphere in presence of one or more catalysts being active in simultaneous non-oxidative and oxidative conversion of ethanol to a product stream with acetic acid; recovering from the product stream a stream of acetic acid; optionally recovering reactive derivatives of acetic acid and recycling these to step (a). | 05-27-2010 |
| 20110137074 | PROCESS FOR THE PRODUCTION OF ACETIC ACID ETHYLENE AND VINYL ACETATE MONOMER - An integrated process for the production of acetic acid, ethylene and vinyl acetate monomer comprising the steps of:
| 06-09-2011 |
| 20110314834 | COMBINED PRODUCTION OF HYDROCARBONS AND ELECTRICAL POWER - A process for the preparation of hydrocarbon products and for the generation of power comprising the steps of (a) providing a synthesis gas having a hydrogen to carbon monoxide ratio of between 0.1 and 1; (b) contacting the synthesis gas with one or more catalysts which together catalyse a reaction of hydrogen and carbon monoxide to oxygenates comprising methanol and dimethyl ether with a dimethyl ether to methanol ratio of higher than 2 and a carbon dioxide content of above 20 mole %; (c) contacting the carbon dioxide containing oxygenate mixture at an inlet temperature of between 240 and 4000 C with a catalyst being active in the conversion of oxygenate to higher hydrocarbons and a tail gas being rich in carbon dioxide; (d) combusting the carbon dioxide rich tail gas, optionally admixed with fresh carbon monoxide rich synthesis gas in a gas turbine combustion chamber to flue gas; and (e) expanding the flue gas stream through a gas turbine for the generation of power. | 12-29-2011 |
