Title: Catalyst for purifying exhaust gas and exhaust gas purifying method
Inventor: IKEDA YASUO
IPC: B01J23/63
Filed: 1998-11-30
Abstract: A catalyst for purifying exhaust is prepared by mixing first powders in which at least Pt is loaded on a f first support and second powders in which at least Rh is loaded on a second support and loading NOx occluding material at least on the first support. In such catalyst, the second support is made of a stabilized zirconia stabilized by alkaline-earth metal or rare-earth element.        The second support, having been become alkaline by the alkaline-earth metal or the rare-earth element, is excellent in absorbing performance of the steam (H2O), so that the steam reforming reaction by Rh advances sufficiently. Therefore, the created hydrogen greatly contributes to the reduction of NOx and to the sulfur poisoning prevention of the NOx occluding material.      Also, the oxidizing ability of Pt is maintained high, Rh sufficiently exhibits the steam reforming reaction activity and the sulfur poisoning of NOx occluding material is restrained.
