Abstract
A catalyst which consists of a carrier and a catalytically active oxide material applied to the surface of the carrier is prepared by a process in which the carrier is first moistened with, as an adhesive liquid, an aqueous solution of an organic substance boiling at above 100.degree. C. at atmospheric pressure and a layer of active oxide material is then bonded to the surface of the moistened carrier by bringing it into contact with dry, finely divided active oxide material and the adhesive liquid is then removed from the moistened carrier coated with active oxide material.
Claims19
A process for the preparation of a catalyst which consists of a carrier and a catalytically active oxide material applied to the surface of the carrier, in which the carrier is first moistened with a liquid binder, a layer of active oxide material is then bound to the surface of the moistened carrier by bringing it into contact with dry, finely divided, active oxide material, and the liquid binder is then removed from the moistened carrier coated with active oxide material, wherein the liquid binder is a solution consisting of from 20 to 90% by weight of water and from 10 to 80% by weight of an organic compound having a boiling point or sublimation temperature at atmospheric pressure of greater than 150.degree. C.
A process for the preparation of a catalyst which consists of a carrier and a catalytically active oxide material applied to the surface of the carrier, wherein a process as claimed in any of one of the preceding claims is repeated periodically.
