| 20090170694 | CATALYST MATERIAL FOR TREATING PRODUCTS PRODUCED DURING COMBUSTION AND METHOD FOR ITS PREPARATION - A catalyst material is provided for treating products created during combustion which is developed for the catalytic conversion of carbon-containing particles, the catalyst material being applied onto a carrier and the catalyst material including cerium as one catalyst component. In order to provide a catalyst material, using which the catalytic conversion of carbon-containing particles is able to be improved, the catalyst components have at least one additional catalyst component besides cerium, the proportion of cerium amounting to at least 92 mol-% with respect to the entire quantity of the catalyst components. A method is also provided for preparing a catalyst material. | 07-02-2009 |
| 20090301048 | Filter for Removing Particles from a Gas Stream and Method for its Manufacture - A filter for removing particles from a gas stream has a filter pad with a coating which contains at least one of the following substances: (a) at least one aluminum oxide selected from alpha-, gamma-, delta- and theta-aluminum oxide, (b) hydrous aluminum oxide which is doped with silicon dioxide, at least one oxide of a metal of the 3 | 12-10-2009 |
| 20100193356 | SENSOR ELEMENT AND METHOD AND MEANS FOR ITS PRODUCTION - A sensor element for gas sensors is described for determining gas components of a gas mixture, especially in exhaust gases of internal combustion engines, having at least one electrochemical measuring cell and at least one porous layer that is exposed to the gas mixture. The porous layer contains palladium, platinum, ruthenium, an alkali metal and/or an alkaline earth metal, the platinum being contained in the porous layer at a minimum concentration of 1.5 wt. %. Furthermore, a method and an impregnating solution are described for producing the sensor element. | 08-05-2010 |
