| titleOfInvention | Method for manufacturing double layer coated Pd only three way catalyst |
| abstract | The present invention relates to a method for producing a palladium tertiary catalyst having a double layer coating structure, using alumina (Al 2 O 3 ), cerium oxide (CeO 2 ), and a mixed solution as an additive. In the process of preparing the catalyst slurry, instead of the conventional method using only cerium oxide, a cerium oxide, a cerium-zirconium composite oxide, and a cerium-zirconium-yttrium composite oxide are used together in the primary catalyst slurry, and the above-mentioned oxidation is performed in the secondary catalyst slurry. Cerium carbonate (Ce (CO 3 ) 2 ) is additionally used in cerium and cerium-zirconium composite oxides and cerium-zirconium-yttrium composite oxides, and then praseodymium oxide (PrO 2 ) is added and a mixed solution is added. and a reaction after which the metal oxide (a perovskite) of (LaCe) (FeCo) O 3 and (LaSr) (FeCo) O, by prepared by three appropriate amount was added to a selected one of a meat-porous in the finished catalyst a secondary coating layer On of More while having improved NOx removal performance and heat relates to a method of producing a three-way catalytic palladium double-layer coating structure that can be produced the amount of the expensive palladium significantly lower than the conventional method. |
