HONEYCOMB CATALYST FOR CARBON MONOXIDE METHANATION, MANUFACTURING METHOD OF THE CATALYST, AND METHANATION METHOD OF CARBON MONOXIDE USING THE CATALYST

摘要

PPROBLEM TO BE SOLVED: To provide a honeycomb catalyst capable of stably and highly efficiently removing carbon monoxide in a hydrogen-containing gas, and to provide the manufacturing method of the honeycomb catalyst. PSOLUTION: The honeycomb catalyst for carbon monoxide methanation is characterized in that a catalyst layer is formed on the surface of a honeycomb base material made of metal or ceramic and comprises a metal and a metal oxide. The metal oxide is at least one kind of oxide or multiple oxide selected from ZrOSB2/SB, CeOSB2/SB, NiO, CoO, CoSB3/SBOSB4/SB, AlSB2/SBOSB3/SB, TiOSB2/SBand SiOSB2/SB, and the metal is at least one kind of metal selected from 4B group, 6A group, 7A group and 8 group. The invention is related to the honeycomb catalyst for carbon monoxide methanation in a hydrogen-containing gas, the manufacturing method of the catalyst and the methanation method of carbon monoxide using the catalyst.
