  • Catalysts having enhanced stability, efficiency and/or activity for alkylene oxide production
    Patent number: 8765630
    Abstract: 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.

  • ALUMINA CARRIERS AND SILVER-BASED CATALYSTS FOR THE PRODUCTION OF ALKYLENE OXIDES
    Publication number: 20110082029
    Abstract: An improved carrier useful for preparing a catalyst having excellent catalytic performance when used in the production of alkylene oxide, such as ethylene oxide. The carrier is obtained by a) impregnating a preformed alpha-alumina carrier with at least one modifier selected from among alkali metal silicates and alkaline earth metal silicates, b) drying the impregnated carrier; and c) calcining dried carrier. The carrier may optionally be washed, prior to being impregnated by conventional catalytic material and/or promoter material.
