Process for applying a catalytically active coating on catalyst supports

Abstract From the Canadian patent

The present invention provides a process for applying a coating or film of catalytically active elements by means of solution on the external surface of a porous catalyst support i.e. a catalyst support having a large surface area character-, ized in that the catalyst support is impregnated with a solution of at least one of various complexing agents precipitants and, reducing agents in an organic liquid without exceeding the, saturation of the catalyst supports the solution of catalytic-, ally active elements is then added the liquid is removed by, heating and when required the catalyst support thus treated is, subjected to an aftertreatment which is treatment with a reducing agent or …
