摘要： PROBLEM TO BE SOLVED: To provide a catalyst for cleaning exhaust gas, the oxygen storage/release capacity of which is improved by using ceria and which restrains the production of H 2 S. SOLUTION: The catalyst for cleaning exhaust gas is composed of a lower catalyst layer which contains a ceria-zirconia compound oxide containing 50-70 mass% CeO 2 and ≥5 mass% Pr 2 O 3 and on which at least one of Pt and Pd is deposited and an upper catalyst layer which contains zirconia at the least and on which Rh is deposited at the least. The total amount of CeO 2 per 1 liter carrier base material is 15-30 g. Since the amount of CeO 2 is small, the catalyst for cleaning exhaust gas restrains the production of H 2 S and the catalyst for cleaning exhaust gas exhibits high oxygen storage/release capacity even if the amount of CeO 2 is small.

摘要： PROBLEM TO BE SOLVED: To satisfactorily reduce and remove NOx in the exhaust gas containing the oxygen of a time-average excess even in the low temperature region and to restrain also NH 3 from being discharged. SOLUTION: A NOx adsorbing/reducing catalyst 3 for adsorbing NOx and reacting the adsorbed NOx with NH 3 to reduce NOx into N 2 is arranged in an exhaust gas flow passage. The exhaust gas atmosphere of R 1 are repeated alternately on the upstream side of the catalyst 3 (wherein R is a molar ratio of NH 3 to NOx). NOx is adsorbed/accumulated in the catalyst 3 in the exhaust gas atmosphere of R 3 and reduced/removed so that the NOx adsorptive ability of the catalyst 3 can be recovered again in the exhaust gas atmosphere of R>1.

摘要： PROBLEM TO BE SOLVED: To reduce exhaustion noise and exhaustion pressure loss while retaining the purification performance of a catalyst at a high level by improving the structure of the honeycomb support itself. SOLUTION: A low-cell-density portion 12 lower in cell density than in the upstream is formed in the downstream in the flowing direction of exhaust gas. The passage for exhaust gas is expanded when exhaust gas flowing into the upstream flows into the low-cell-density portion 12, leading to a silencing effect due to expansion of the passage, like in common silencers, and the reduction of the pressure loss.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas-purifying method wherein by employing ceria, oxygen-absorbing/releasing function is improved, and generation of H 2 S is suppressed. SOLUTION: A catalyst used in the purifying method includes a lower catalytic layer which contains a ceria-zirconia compound oxide containing 50-70 mass% of CeO 2 and on which at least either one of Pt and Pd is carried, and an upper catalyst layer which contains at least zirconia and on which at least Rh is carried. The total weight of CeO 2 per liter carrier base material is 15-30 g to perform alternately rich and lean controls. Since the amount of CeO 2 is small, generation of H 2 S is suppressed, and even if the amount of CeO 2 is small, a high oxygen absorbing/releasing function can be exhibited.
