SMR Manufacturing method for catalyst coated on metal foam for SMR reaction and catalyst coated on metal foam manufactured thereby

摘要

TECHNICAL FIELD The present invention relates to a porous metal-coated nickel-based catalyst for SMR reaction with improved catalyst adhesion and reaction characteristics, and a method for producing and using the same. The present invention relates to a method for preparing nickel-containing composite particles, comprising the steps of: preparing nickel-containing composite particles carrying a metal active component on a ceramic support; A second step of preparing a nickel-based catalyst slurry having a pH of 4 to 8 by adjusting the average diameter of the nickel-containing composite particles to 15 μm or less by mixing the nickel-containing composite particles and the inorganic binder and then milling; And a third step of dip-coating the nickel-based catalyst slurry on the porous metal body, followed by drying and firing, to prepare a nickel-based catalyst having the nickel-containing complex supported on the porous metal body. to provide. According to the present invention, it is possible to improve the adhesion of the catalyst supported on the ceramic substrate coated on the metal foam, and to improve the reaction efficiency.
