The invention is a catalyst formed by covering each surface of particles in a ceramic support with an alumina thin film and holding an active catalyst component with the surface of the thin film, which is large in the pore size and porosity and small in the pressure loss irrespectively of forming the alumina thin film on the surface and is produced, for example, by immersing the ceramic support in an aluminum-containing metallic compound, preliminarily firing, immersing in hot water, drying, firing and finally holding the active catalyst component on the alumina thin film on the surface of the support.

Catalyst and method for preparation thereof

A method of producing a catalyst carrier. The method comprises contacting a silicon-containing ceramic material with a solution of an aluminum containing metal compound, firing the resulting material, immersing the material in hot water and, again firing the material.

Catalyst carrier and method of producing same

A catalyst carrier which comprises particles of a silicon-containing ceramic material. Each of these particles is covered by a film of alumina on which a noble metal is carried.

It is to provide a catalyst carrier having large pore size and porosity and a small pressure loss. The catalyst carrier is characterized by covering a surface of each particle in a silicon-containing ceramic carrier with alumina thin film, and is produced by immersing a carrier having an oxide film of a silicide in its surface in a solution of aluminum containing metal compound, drying by heating, calcining, subjecting to an immersion treatment in hot water and thereafter firing.
