Abstract
The present invention discloses an improved supported catalyst for gas purification which comprises a catalyst carrier composed of a molded body including alumina cement having a CaO component in an amount of less than 40% by weight, an Al.sub.2 O.sub.3 component in an amount of more than 35% by weight and an iron oxide component in an amount of less than 20% by weight. Additionally, catalytic materials and auxiliary materials may be added, depending on necessity. A platinum group metal is then supported on the catalyst carrier. There is also disclosed a method for manufacturing such catalyst. .Iadd.
