摘要： PROBLEM TO BE SOLVED: To provide an NOx sorption and reduction catalyst which has a high NOx sorption capacity even after a high-temperature durability test (750 deg.C×5 hr), can sufficiently sorb NOx in a temperature range above 600 deg.C, and can exhibit a high NOx reduction rate and to provide a method for using the same. SOLUTION: This catalyst is prepared by infiltrating a noble metal and an NOx sorbent into a coat layer based on a support comprising a compound oxide having a magnesia/alumina spinel structure and a specific surface area of at least 50 m2/g and containing 8-20 wt.% alumina binder. The support is strongly basic and lowly reactive with the sorbent, so that the consumption of the sorbent by the reaction with the support can be reduced. Even when the sorbent undergoes a volume change after repeated NOx sorption and reduction, the alumina binder prevents the coat layer form being peeled.

摘要： PROBLEM TO BE SOLVED: To obtain a catalyst for the purification of exhaust gas used for reducing and removing NOx contained in exhaust gas containing excess oxygen and capable of retaining high catalytic activity even to SOx-containing exhaust gas over a long period of time. SOLUTION: The catalyst contains a powdery porous oxide with a supported noble metal, powdery ZSM-5 and a powdery CeO2-ZrO2 solid solution. Since the noble metal is previously supported on the powdery porous oxide, the probability of contact of the noble metal with the ZSM-5 and the CeO2-ZrO2 solid solution lowers. Since the ZSM-5 is excellent in HC adsorptivity and the CeO2-ZrO2 solid solution has high oxygen occluding and discharging ability and high heat resistance, the covering of the noble metal with accumulated SOx as well as the grain growth of the noble metal is suppressed.

摘要： PROBLEM TO BE SOLVED: To suppress the discharge of a sulfate component (granular material) even at low temp. area. SOLUTION: A reducing agent is supplied to waste gas and the waste gas is brought into contact with an SOx catalytic reducing catalyst consisting essentially of a transition element to partially oxidize at least the reducing agent to partially oxidized hydrocarbon, and also the sulfate component in the waste gas is reduced and purified with the partially oxidized hydrocarbon. The partially oxidized hydrocarbon is very high in reaction activity and selectively reduces the sulfate component by reacting with the sulfate component in the waste gas. Therefore, the sulfate component is suppressed from being discharged as granular material since the sulfate component is efficiently reduced and discharged as SO2.
