摘要： PROBLEM TO BE SOLVED: To provide a shift catalyst capable of sufficiently suppressing the progression of deterioration even under conditions of a high temperature and oxidation atmosphere. SOLUTION: A porous oxide body is prepared (step S100) and Pt is carried thereon (steps S110 and S120) and further an additive metal, such as Mo, is carried thereon (steps S130 and S140). Thereafter, a CeO 2 film-like part covering part of at least the Pt is formed (steps S150 and S160) and is shaped (step S170) to complete the shift catalyst. The shift catalyst having excellent durability is obtained by forming the CeO 2 film-like part. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To exhibit a high CO shift reaction activity even in exhaust gas from an internal combustion engine of a lean combustion system, in a reaction condition of a large space velocity.
SOLUTION: In the catalyst comprising a carrier with ceria as a principal component and a noble metal carried on the carrier, the cerium atom in the carrier is fixed to tervalent. Thus, oxygen occlusion/releasing capacity is reduced, to suppress consumption of CO by oxidation with oxygen released in a reduction atmosphere.

摘要： PROBLEM TO BE SOLVED: To improve the reduction/purification efficiency of NOx by controlling the sulfur poisoning of the NOx absorbent of an exhaust gas purifying catalyst. SOLUTION: In this purification method, an exhaust gas purifying catalyst in which a noble metal and an NOx absorbent are supported on a porous carrier is used. When the air fuel ratio of the mixed gas of fuel to be supplied to an internal combustion engine and air is lean, NOx in exhaust gas is absorbed in the catalyst, and when the air fuel ratio is stoichiometric-rich, the absorbed NOx is reduced into N2 by a reducing gas in the exhaust gas and the noble metal. Hydrocarbons are added steadily to the catalyst in a concentration range in which a hydrocarbons concentration is at the lowest 1000 ppm, and lower than a value which makes the air fuel ratio of a lean mixed gas to be supplied to an internal combustion engine stoichiometric.

CONSTITUTION: A catalyst for purifying exhaust gas, in which Rh is supported on a zeolite at the same time as Pt, at the latest, is brought into contact with oxygen-excessive exhaust gas to which HC has been added to reduce and remove NOx contained in the exhaust gas. Since the particle size of Pt becomes larger than 10nm and addition effect of Rh is effected, purification efficiency of NOx can be improved.
