  • Publication number: 20240216894
    Abstract: The present invention provides a composite catalyst for diminishing energy demand during carbon dioxide absorbent regeneration and a method for producing the same. The present invention more particularly relates to a composite catalyst in which the surface or inside of activated carbon activated carbon used as a porous carrier is modified with oxides of one or more metals selected from a transition metal group consisting of Fe, Ni, and Mo, and a method for producing the composite catalyst. The activated carbon composite catalyst modified with a metal of the present invention is able to regenerate MEA (monoethanolamine) at a low temperature of 100° C. or below to diminish heat consumption, can decrease the heat duty by increasing the carbon dioxide desorption rate at a low temperature of 100° C.
