    摘要： A process for producing an exhaust-gas-purifying catalyst includes the steps of immersing a porous support into a solution including a noble metal catalyst ingredient, thereby preparing a support with a noble metal catalyst ingredient loaded thereon, and thermally treating the noble-metal-catalyst-ingredient-loaded support at a temperature of 800.degree. C. or more in non-oxidizing atmosphere. In the thermally-treating step, the noble metal catalyst ingredient is prevented from being oxidized to its oxide, and accordingly it is inhibited from migrating in vapor phase. Further, in the thermally-treating step, pores of the porous support are contracted so that they surround the noble metal catalyst ingredient closely therein. All in all, the noble metal catalyst ingredient is prevented from sintering. Thus, the resulting exhaust-gas-purifying catalyst is of superb heat-resistance, and it can be applied to elevated temperatures of 800.degree. C. or more in fuel-lean atmosphere.

    摘要： An exhaust gas purifying apparatus, including an NOx occlusion reduction catalyst (2) and a filter catalyst (3) arranged in series, is used, and the exhaust gas is allowed to flow from the NOx occlusion reduction catalyst (2) to the filter catalyst (3) in a normal flow process, and, in a recovery process for allowing exhaust gas added with a reducing agent to flow, the flow direction of the exhaust gas is reversed toward the NOx occlusion reduction catalyst (2) from the filter catalyst (3). Since the exhaust gas is heated by reaction heat of the filter catalyst (3), the NOx occlusion reduction catalyst (2) can recover from sulfur poisoning in the exhaust gas at a low temperature. Thereby, overheating of the filter catalyst (3) is prevented. Therefore, recovery from sulfur poisoning can be improved, and also deterioration and breakage of the filter catalyst can be prevented.
