    摘要: A carrier for an ethylene epoxidation catalyst is provided that includes an alumina first component and a mixed metal oxide of alumina second component. The mixed metal oxide of alumina second component comprises a corundum lattice structure having a plurality of O—Al—O bonds, wherein an Al atom of at least one O—Al—O bond of the plurality of O—Al—O bonds, but not all of the plurality of O—Al—O bonds, is replaced with a divalent or trivalent transition metal selected from the group consisting of scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni) copper (Cu), and zinc (Zn). A catalyst containing the carrier, as well as a process for the epoxidation of ethylene using the catalyst are also disclosed.

    摘要: A method for lowering the sodium content of different carriers which may have different physical properties as well as varying degrees of sodium is provided. The method, which lowers the sodium content from the surface, subsurface as well as the binding layer of the carrier, includes contacting a carrier with water. A rinse solution is recovered from the contacting. The rinse solution includes leached sodium from the carrier. The sodium content in the rinse solution is then determined. The contacting, recovering and determining are repeated until a steady state in the sodium content is achieved.
