SMR Ni-based catalyst for SMR reaction coated on metal foam with improved catalyst adhesion and reaction property and Manufacturing method and Use thereof

摘要

The present invention relates to a metal porous body-coated Ni based catalyst for SMR reaction with improved catalyst adhesion and reaction characteristics, and a production method and use thereof. More specifically, the present invention provides a production method of the metal porous body-coated Ni based catalyst, the method comprising: a first step of preparing nickel-containing composite particles in which a metal activating component is supported on a ceramic support; a second step of mixing the nickel-containing composite particles with an inorganic binder to obtain a mixture, and milling the mixture to prepare a Ni-based catalyst slurry; a third step of pretreating the surface of a metal porous body so that an Al_2O_3 oxide film is formed on the surface of the metal porous body, or the Al_2O_3 oxide film will be formed on the surface of the metal porous body in a later step; and a fourth step of dip-coating the pretreated metal porous body with the Ni-based catalyst slurry, drying and firing the pretreated metal porous body dip-coated with the Ni-based catalyst slurry to produce a Ni-based catalyst in which a nickel-containing composite is supported on the metal porous body having the Al_2O_3 oxide film formed on the surface thereof. According to the present invention, the method can maintain adhesion and reactivity of the metal porous body-coated catalyst even after a metal porous body-coated catalyst has been used in steam-methane reforming reaction by pretreating the metal porous body.
