Title:
METHANATION CATALYST AND METHOD FOR PRODUCING METHANE USING THE SAME
Document Type and Number:
Japanese Patent JP2023175339
Kind Code:
A
Abstract:
To provide a methanation catalyst that has a low light-off temperature T50 and exhibits superior catalytic activity at low temperatures (for example, 240°C or lower).SOLUTION: A methanation catalyst includes CeO2 fine particles with an average particle size of from 10 to 30 nm as determined by powder X-ray diffraction measurement, and NiO fine particles with an average particle size of from 20 to 50 nm as determined by powder X-ray diffraction measurement. The ratio of the average particle size of the NiO fine particles to the average particle size of the CeO2 fine particles (NiO/CeO2) ranges from 1.4 to 3.0.SELECTED DRAWING: None
