摘要： PROBLEM TO BE SOLVED: To provide a novel catalyst device capable of efficiently converting ammonia to N2 within a wide temp. range and a high SV region to purify the same. SOLUTION: A catalyst high in the max. conversion temp. oxidizing ammonia to convert the same to nitrogen to maximize a conversion ratio is arranged on the upstream side of an exhaust gas passage and a catalyst low in the max. conversion temp. is arranged on the downstream side of the exhaust gas passage. Within a low temp. region, ammonia is not almost purified by the catalyst on the upstream side but purified by the catalyst on the downstream side and, within a high temp. region, ammonia is mainly purified by the catalyst on the upstream side to be converted to nitrogen.

摘要： PROBLEM TO BE SOLVED: To restrain a high cleaning ratio of NOx which is practically allowable even after endurance at a high temperature in purifying exhaust gas containing sulfur oxide in an oxygen surplus atmosphere. SOLUTION: The above exhaust gas is brought into contact with a catalyst for cleaning exhaust gas with at least one kind of metal selected from rare earth metals, and at least one kind of metal selected from transition metals such as Fe, Ni, Co and Mn carried together with noble metals. The two or more carried metals take SO2 contained in the exhaust gas into the catalyst as multiple sulfate. The multiple sulfate produced in this way is easy to be decomposed at a low temperature in a stoichiometrically enriched atmosphere compared with the case of sulfate produced by a single metal, so that the effect of occluding NOx in rare earth metals can be given once more.
摘要翻译：要解决的问题：为了抑制即使在高温下耐久性中在氧气余量中净化含有氧化硫的废气中也可以实际容许的高清洁率。解决方案：使用选自稀土金属中的至少一种金属和选自Fe，Ni，Co和Mn等过渡金属中的至少一种金属，使上述废气与用于清除废气的催化剂接触携带贵金属。两种或多种携带的金属将废气中所含的SO 2作为多重硫酸盐进入催化剂。与以单一金属生产的硫酸盐的情况相比，在化学计量浓度大的气氛中，以这种方式生产的多重硫酸盐易于在低温下分解，从而可以再次给予NOx在稀土金属中的吸附效果。

摘要： PURPOSE:To keep high purification rate of NOx being practically allowable even durable use at high temp. in purification of an exhaust gas under excess oxygen atmosphere. CONSTITUTION:An excess oxygen-contg. exhaust gas is brought into contact with a catalyst for purification of the exhaust gas carried on a carrier consisting of a porous body carrying at least two metals selected from rare earth metals and at least one of Pt and Pd. SO2 contained in the exhaust gas is taken into the catalyst as a composite sulfate by means of the carried plurality of rare earth metals and as the formed composite sulfate tends to be easily decomposed at lower temp. in a atmosphere of a stoichimetric mixture to a fuel-rich mixture in comparison with a sulfate formed of a single metal, it is possible to exhibit again NOx occlusion effect of the rare earth metal.
