Abstract
Provided is a methanation catalyst processing method capable of suppressing degradation of a catalyst performance. A methanation catalyst processing method of the present disclosure includes oxidizing nickel through a heat treatment of a methanation catalyst by supplying an oxygen gas containing oxygen to a reactor, the reactor housing the methanation catalyst containing the nickel as a catalyst component. In the oxidizing, the oxygen gas is supplied to the reactor such that the oxygen is supplied to 1 g of the methanation catalyst at a supply rate in a range of from 0.0213 mmol-O/sec·g-cat. to 0.0638 mmol-O/sec·g-cat., and a time period of the heat treatment of the methanation catalyst by supplying the oxygen gas to the reactor is set to 30 minutes or more.
