A PROCESS FOR PREPARING A CATALYST WITH A HIGHLY DISPERSED CATALYTICALLY-ACTIVE COATING

摘要

The invention relates to a process for preparing a catalyst which has a catalytically-active coating of high surface area finely-divided materials and catalytically-active components on an inert support structure. A powder mixture of the finely-divided materials used is impregnated with a solution of precursor compounds of the catalytically-active components. By suitable combination of the finely-divided materials and the precursor compounds, and appropriate management of the impregnation process, a highly dispersed deposition and adsorption of the catalytically-active components is ensured on the finely-divided materials. Then an aqueous coating dispersion is produced using the impregnated powder mixture, and the support structure is coated therewith. The coating is then dried and calcined.
