A catalyst for the manufacture of alkylene oxide, for example ethylene oxide, by the vapor-phase epoxidation of alkene containing impregnated silver and at least one efficiency-enhancing promoter on an inert, refractory solid support, said support incorporating a sufficient amount of zirconium component (present and remaining substantially as zirconium silicate) as to enhance at least one of catalyst activity, efficiency and stability as compared to a similar catalyst which does not contain the zirconium component.
L'invention concerne un catalyseur destiné à la production d'oxyde d'alkylène, par exemple d'oxyde d'éthylène, par époxydation d'alcène en phase vapeur qui contient de l'argent imprégné et au moins un promoteur d'augmentation d'efficacité d'un support solide réfractaire, inerte ; ledit support comprenant une quantité suffisante d'un composant zirconium (présent et demeurant sensiblement à l'état de silicate de zirconium) afin d'accroître l'activité, l'efficacité et la stabilité du catalyseur en comparaison avec un catalyseur identique ne contenant pas le composant zirconium.
