[54] CARRIER TREATMENT TO IMPROVE CATALYTIC PERFORMANCE OF AN ETHYLENE OXIDE CATALYST
[57] 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.
