METHOD FOR PRODUCING AMMONIA DECOMPOSITION CATALYST

Title:

METHOD FOR PRODUCING AMMONIA DECOMPOSITION CATALYST

Document Type and Number:

Japanese Patent JP2012223769

Kind Code:

A

Abstract:

To provide a method for producing an ammonia decomposition catalyst with which ammonia of a wide concentration range from low concentration to high concentration can be efficiently decomposed.

The ammonia decomposition catalyst contains: at least one element (active element) selected from the group comprising group 8-10 elements; a compound (addition component A) of an element having ≤1.3 Pauling's electronegativity; and a metal oxide. The method for producing the ammonia decomposition catalyst for converting ammonia into nitrogen and hydrogen comprises the steps of: measuring the amount (volume) of water to be absorbed in the metal oxide when producing the catalyst; impregnating the metal oxide with a solution the concentration of which is adjusted so that the amount of the active element to be impregnated becomes the measured volume exactly; and treating the impregnated metal oxide with hydrogen.
