| abstract |
The present invention relates to a molded article having a honeycomb structure of a ferrite metal oxide catalyst using a spray pyrolysis method and a method for manufacturing the same, and more particularly, a metal oxide precursor including iron as a main catalyst and magnesium, zinc or manganese as a cocatalyst. Method for preparing a catalyst compact coated with a metal oxide catalyst powder prepared by spray pyrolysis from a carrier or monolith, and a compact directly extruded in a honeycomb form, and through the oxidative dehydrogenation of n -butene using the same. A method for producing butadiene. |
