Abstract: A method is provided for improving the performance of a silver-based epoxidation catalyst comprising a carrier. The carrier includes at least 80 percent alpha alumina and has a pore volume from 0.3 mL/g to 1.2 mL/g, a surface area from 0.3 m2/g to 3.0 m2/g, and a pore architecture that provides at least one of a tortuosity of 7 or less, a constriction of 4 or less and a permeability of 30 mdarcys or greater. A catalytic amount of silver and a promoting amount of one or more promoters is disposed on and/or in said carrier. The method further includes the steps of initiating an epoxidation reaction by reacting a feed gas composition containing ethylene and oxygen present in a ratio of from about 3.5:1 to about 12:1, in the presence of the silver-based epoxidation catalyst at a temperature of about 200° C. to about 230° C., and subsequently increasing the temperature either stepwise or continuously.

Abstract: Oxalic acid is employed in a precursor mixture containing at least one milled alpha alumina powder having a particle size of 0.1 to 6 microns, boehmite powder that functions as a binder of the alpha alumina powders, and at least one burnout material having a particle size of 1-10 microns to provide a porous body having enhanced pore architecture in which extrusion cracks can be reduced. The presence of oxalic acid in such as precursor mixture can reduce and even eliminate NOx emission during a high temperature heat treatment process.
