Document Type and Number:
Japanese Patent JP4668757
Kind Code:
B2
Abstract:
[Problem to be solved] To provide a method of stabilizing a catalyst enabling the stabilization to be completed in a very short period of time by means of a simple process, particularly a method of stabilizing a reduced Ni-containing catalyst. [Solution] A method of stabilizing a reduced Ni-containing catalyst, where gas in which three kinds of O 2 , H 2 O, and CO 2 coexist, or gas in which four kinds of O 2 , H 2 O, CO 2 , and inert gas coexist is introduced into the reduced Ni-containing catalyst at a temperature of not less than 0.1°C, and of less than 100°C will make it possible to prepare a stable catalyst even in the air.
