| 20090005464 | Method for Producing Olefins from Synthesis Gas in a Reaction Column - Process for the synthesis of olefins from synthesis gas in the presence of at least one Fischer-Tropsch catalyst in a reaction column, wherein the synthesis gas is introduced into the reaction column below a zone A of the reaction column and the olefins formed are taken off below the inlet for the synthesis gas. | 01-01-2009 |
| 20090030235 | METHOD FOR FRACTIONATING STEREOISOMERIC COMPOUNDS - The present invention relates to a method for fractionating stereoisomeric compounds which have at least one alcohol and/or amino group. | 01-29-2009 |
| 20090143601 | METHOD FOR PREVENTING FUMARIC ACID DEPOSITS IN THE PRODUCTION OF MALEIC ACID ANHYDRIDE - The present invention provides a process for preventing fumaric acid deposits in the preparation of maleic anhydride, comprising the following steps: | 06-04-2009 |
| 20100081804 | PROCESS FOR CONTINUOUS HYDROGENATION OR HYDROGENATING AMINATION - A process is described for continuously hydrogenating unsaturated compounds, in which particles of a first hydrogenation catalyst are suspended in a liquid phase in which an unsaturated compound is dissolved, the liquid phase, in the presence of a hydrogenous gas at a first partial hydrogen pressure and at a first temperature, is conducted through a packed bubble column reactor in cocurrent counter to the direction of gravity, the effluent from the bubble column reactor is sent to a gas-liquid separation, the liquid phase is sent to a crossfiltration to obtain a retentate and a filtrate, the retentate is recycled into the bubble column reactor and the filtrate, in the presence of a hydrogenous gas at a second partial hydrogen pressure and at a second temperature, is passed over a bed of a second hydrogenation catalyst, wherein the second partial hydrogen pressure is at least 10 bar higher than the first partial hydrogen pressure. | 04-01-2010 |
| 20100113805 | PROCESS FOR OBTAINING MALEIC ANHYDRIDE BY DISTILLATION - What is described is a process for obtaining maleic anhydride by distillation from a solution of maleic anhydride in a high-boiling absorbent which has been obtained by gas phase oxidation of a hydrocarbon and at least partial absorption of the oxidation products into the absorbent, by
