摘要： A process serves for recoating a deactivated catalyst coating of a catalyst for converting harmful constituents from the exhaust gas of an internal combustion engine, particularly in a motor vehicle. In this process, washcoat and/or noble metal compounds are sprayed by means of an aerosol into the catalyst. The noble metal compounds are subsequently brought into their elemental state by means of a reducing medium flowing through the catalyst, after which the washcoat applied is dried by heat treatment or calcination. In an apparatus for carrying out the process, a first line for a carrier gas and a second line for the washcoat and/or the noble metal compounds are provided. The first line is arranged at least partly in a region before the catalyst within the second line and at its ends nearest the catalyst is provided with an atomization device. The second line opens into the catalyst,with there being provided after the catalyst a third line which opens into a separator from which the first and the second lines lead away.
摘要翻译：一种方法用于重新涂覆催化剂的失活的催化剂涂层，用于转化来自内燃机，特别是机动车辆的废气的有害成分。在该方法中，将修补基面涂层和/或贵金属化合物通过气溶胶喷射到催化剂中。贵金属化合物随后通过流过催化剂的还原介质进入其元素状态，之后涂覆的修补基面涂层通过热处理或煅烧进行干燥。在用于实施该方法的装置中，提供了用于载气的第一线和用于修补基面涂层和/或贵金属化合物的第二线。第一管线至少部分地布置在第二管线内的催化剂之前的区域中，并且其最靠近催化剂的端部设置有雾化装置。第二条线进入催化剂，在催化剂之后设置第三条线，该第三条线通向第一和第二条线路从该分离器通过。
