| 20090101584 | Reverse flow reactor with integrated separation and process for the employing this reactor - The present invention pertains to a reverse-flow reactor comprising at least one catalyst bed which is preceded and followed by at least one bed containing selectively adsorbing material, and its application for in a process for the removal of contaminants from a process stream. | 04-23-2009 |
| 20100217038 | PROCESS FOR CONVERTING LEVULINIC ACID INTO PENTANOIC ACID - A process for converting levulinic acid into pentanoic acid, the process comprising the following steps: (a) contacting a feedstock comprising levulinic acid under hydrogenating conditions, in the presence of hydrogen, with a non-acidic heterogeneous hydrogenation catalyst comprising a hydrogenation metal supported on a solid catalyst carrier to obtain a first effluent comprising gamma valerolactone; (b) contacting at least part of the first effluent under hydrogenating conditions, in the presence of hydrogen, with a strongly acidic catalyst and a hydrogenation metal to obtain a second effluent comprising pentanoic acid, wherein step (b) is operated at a conversion per pass of at most 70 wt % to obtain the second effluent comprising pentanoic acid and unconverted gamma valerolactone, and wherein part of the unconverted gamma valerolactone is recycled to step (a) and/or step (b). | 08-26-2010 |
| 20100292507 | PROCESS FOR CONVERTING LEVULINIC ACID INTO PENTANOIC ACIDITLE - A process for converting levulinic acid into pentanoic acid, comprising the following steps: (a) supplying hydrogen and a feedstock comprising levulinic acid to a first catalytic zone comprising a strongly acidic catalyst and a hydrogenation metal; (b) converting, in the first catalytic zone, the levulinic acid at a temperature in the range of from 100 to 250° C. into gamma valerolactone to obtain a first effluent comprising gamma valerolactone; (c) supplying at least part of the first effluent to a second catalytic zone comprising a strongly acidic catalyst and a hydrogenation metal; and (d) converting, in the second catalytic zone, gamma valerolactone into pentanoic acid at a temperature in the range of from 200 to 350° C. to obtain a second effluent comprising pentanoic acid, wherein the conversion temperature in the first catalytic zone is lower than the conversion temperature in the second catalytic zone, and wherein the acidic catalyst and the hydrogenation metal in the first catalytic zone has the same composition as the acidic catalyst and the hydrogenation metal in the second catalytic zone. | 11-18-2010 |
