Patent ID: 10882033

Abstract:
A slurry composition for a catalyst and a method for producing the same, a catalyst and a method for producing the same using the slurry composition for a catalyst. The method omits many heretofore required treatment steps and reduces catalyst production cost. The method comprising the steps of providing a slurry composition for a catalyst, comprising at least an aluminosilicate, Cu, and water, and having a solid concentration of 0.1% by mass to 90% by mass, wherein a component for a catalyst has composition represented by Al2O3·xSiO2·yT2O·zCuO (wherein T is a quaternary ammonium cation, and x, y and z are numbers that satisfy 10≤x≤40, 0.1≤y<2.0, and 0.1≤z<2.0, respectively) in terms of molar ratio based on an oxide; coating at least one side of a support with this slurry composition; and heat-treating at 350° C. or higher.
