Title:
CARBON DIOXIDE OCCLUSION REDUCTION TYPE CATALYST
Document Type and Number:
Japanese Patent JP2023157643
Kind Code:
A
Abstract:
To provide a CO2 occlusion reduction type catalyst which exhibits excellent CO2 occlusion performance and methanation catalytic activity even at a low temperature.SOLUTION: A carbon dioxide occlusion reduction type catalyst contains: a porous carrier comprising a metal oxide and having an average pore diameter of 3-50 nm and pore volume of 0.3-1.5 cm3/g; ruthenium supported on the porous carrier; and an alkali metal supported on the porous carrier. A content of the ruthenium is 1-5 pts.mass based on 100 pts.mass of a total content of the porous carrier and the ruthenium. A content of the alkali metal is 2.8-4.5 mass% in terms of oxide based on the whole catalyst.SELECTED DRAWING: None
