    Abstract: 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.

    Abstract: 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.

    Abstract: A silver impregnation solution comprising: (i) silver ions, (ii) a silver concentration enhancer selected from at least one ammonium salt having an anionic component that is thermally decomposable; or at least one amino acid, or a combination thereof, (iii) at least one organic amine; and (iv) water; wherein said components (i)-(iii) are dissolved in said impregnation solution, and oxalic acid may or may not be included. The silver impregnation solution can achieve significantly higher silver concentrations, including at least or above 33, 34, or 35 wt %. Methods for producing a silver catalyst by silver impregnation of a refractory support followed by calcination are also described. The resulting silver catalysts possess high silver loadings of typically at least 17, 18, or 19 wt %.
