Ni-based Catalyst for Tri-reforming of Methane and Its Catalysis Application for the Production of Syngas

摘要

The present invention relates to a triple-reforming of methane using a synthesis gas for producing the nickel-based catalyst and a catalyst according to the triple-reforming of methane, as more particularly to a nickel-containing catalyst of nickel is supported as an active metal on the zirconia carrier, the to the zirconia carrier yttrium metal required and the layer is doped with (dopping) a mixture containing a metal selected from the lanthanide elements and alkaline earth metal elements of metal to induce twisting of the zirconia crystal lattice facilitate the movement of oxygen ion, and the storage of oxygen and triple modification of is to facilitate the supply suppress the carbon deposition on the nickel active metal surface using the active hold and obtain an effect of extending the life of the catalyst, and in particular carbon dioxide, a mixture of oxygen and water vapor gas of the catalyst with an oxidizing agent the methane (tri-reforming) it is used as a reaction catalyst synthesis gas in hydrogen and the ratio of carbon monoxide (H ₂ / CO) for selectively adjusting the available nickel-based catalyst with methane triple reforming to synthesis gas over a nickel-based catalyst of the It relates to a method for manufacturing. ; Yttrium, lanthanide and alkaline earth metal, zirconia carrier, nickel, methane, triple reforming, synthesis gas
