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.

Catalysts having enhanced stability, efficiency and/or activity for alkylene oxide production

The invention provides a method for removing mercury from a liquid or gas hydrocarbon stream, mixtures thereof, including mixtures of liquid streams with a solid carbonaceous substance, by contacting the hydrocarbon stream with a composition comprising silver and a support material, wherein the composition as measured by ammonia chemisorption has a surface acidity in the range of 0.1-10.0 &#x3bc;mole of irreversible NH/g of the composition.

Method for removal of mercury from hydrocarbon feedstocks

Catalysts for the epoxidation of alkene, especially ethylene, to the corresponding alkylene oxide, e.g., ethylene oxide, which catalysts contain a high silver content on carriers having a high surface area and a high pore volume are disclosed. Methods for making and using such catalysts are also disclosed.
