| 20090054227 | METHOD FOR OBTAINING A HOMOGENEOUS FILTERING STRUCTURE FOR A CATALYTIC APPLICATION - The invention relates to a method of obtaining a homogeneous filtering structure for a catalytic application, which can be used as a particulate filter in an internal combustion engine exhaust line, said structure comprising a plurality of honeycomb filter elements in which a homogeneity criterion characteristic of the constituent support material of said elements, in the absence of a catalytic coating, is determined in a prior step, and then the elements making up the structure are selected by means of this homogeneity criterion so as to obtain a structure suitable for homogeneous deposition, within an element and from one element to another, of a catalyst for treating the pollutants in gas phase. | 02-26-2009 |
| 20090163354 | PURIFICATION STRUCTURE INCORPORATING AN ELECTROCHEMICAL CATALYSIS SYSTEM - The invention relates to a structure for the purification of a contaminated gas, for example the exhaust gas from a diesel or petrol engine, the structure incorporating an electrochemical system for treating said gas, composed of an NO | 06-25-2009 |
| 20100083645 | METHOD FOR OBTAINING A POROUS STRUCTURE BASED ON SILICON CARBIDE - The invention relates to a process for obtaining a structure made from a porous ceramic material comprising at least 95% of silicon carbide SiC, said process being characterized in that said structure is obtained from a mixture of SiC grains comprising at least:
