    摘要： A catalyst body comprising a carrier and a catalyst layer containing an alkali metal and/or an alkaline earth metal, loaded on the carrier, which catalyst further contains a substance capable of reacting with the alkali metal and/or the alkaline earth metal, dominating over the reaction between the main components of the carrier and the alkali metal and/or the alkaline earth metal. With this catalyst body, the deterioration of the carrier by the alkali metal and/or the alkaline earth metal is prevented; therefore, the catalyst body can be used over a long period of time.

    摘要： A catalyst for exhaust gas purification includes (1) a monolithic carrier having passages and (2) palladium-loaded alumina obtained by immersing alumina in a palladium solution and then firing the resulting alumina and loaded on the monolithic carrier as a catalyst layer. In the catalyst, the catalyst layer loaded on the partition walls of the passages of the monolithic carrier has a thickness of 5 to 100 &mgr;m and the palladium/alumina (Pd/Al2O3) weight ratio in the catalyst layer is 0.03 to 0.30. This catalyst is a Pd-only catalyst improved in hydrocarbon purifiability during the cold start of engine.

    摘要： A carrier having a specific structure, characterized in that it has alumina and, optionally, a substance liable to react with an alkali metal and/or an alkaline earth metal both used as a catalyst component and/or an alkali metal and/or an alkaline earth metal, which are disposed in the carrier or on the cell wall surface of the carrier; a method for production of the carrier; and a catalyst body comprising the carrier and a catalytic material coated thereon. The use of the carrier allows production of a catalyst body which comprises the carrier and a catalytic material coated thereon, containing an alkali metal and/or an alkaline earth metal, such as Li, Na, K, Ca or the like and which is less susceptible to the deterioration of the carrier caused by the above metal even when used over a long period of time.
