METHOD OF PRODUCING METALLIC CATALYST CARRIER AND DEVICE OF PRODUCING METALLIC CATALYST CARRIER

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a metallic catalyst carrier that produces a metallic catalyst carrier by connecting metal materials together by diffusion junction, the method having excellent mass productivity.SOLUTION: A method of producing a metallic catalyst carrier 1 includes bringing a first metal plate 3 and a second metal plate 5 into contact with each other, applying heat treatment to them in an atmosphere of argon gas, and controlling carbon monoxide concentration at a level lower than or equal to 50 ppm.
