PROCESSO PARA PREPARAR UM CATALISADOR DE PRATA SOBRE UM MATERIAL SUPORTE INERTE,CATALISADOR E PROCESSO PARA PREPARAR OXIDO DE ETILENO E PARA PREPARAR FORMALDEIDO

摘要

A silver catalyst on an inert carrier material, is prepared by precipitating silver ions from a solution by reduction to metallic silver in the presence of an inert carrier material. The reduction is mainly effected by means of reducing agent for the silver ions, which is present on the surface of the inert carrier material in the form of an oxidizable metal and/or metal compound.
