| 20080306298 | Method for Manufacturing Palladium-Containing Catalyst - The present invention provides: a palladium-containing supported catalyst which is used for producing an α,β-unsaturated carboxylic acid from an olefin or an α,β-unsaturated aldehyde in high selectivity; a method for manufacturing the catalyst; and a method for producing an α,β-unsaturated carboxylic acid in high selectivity. In particular, the present invention resides in a method for manufacturing a palladium-containing supported catalyst for producing an α,β-unsaturated carboxylic acid from an olefin or an α,β-unsaturated aldehyde, comprising the step of reducing palladium oxide contained in a catalyst precursor wherein at least the palladium oxide is supported on a carrier. By using such a palladium-containing supported catalyst, an α,β-unsaturated carboxylic acid is produced through liquid-phase oxidation of an olefin or an α,β-unsaturated aldehyde with molecular oxygen. | 12-11-2008 |
| 20090014900 | Equipment and process for the production of carbonated water - A process for producing carbonated water having a high concentration, inexpensively and easily, involves using a static mixer having 20 to 100 elements so as to provide a value Re×N of 100,000 to 2,000,000, in with Re represents a Reynolds number, when a mixture of water and carbonic acid gas flow in the static mixer. | 01-15-2009 |
