ABSTRACT:
This invention relates to a process for the preparation of an ethylene oxide catalyst having improved selectivity stability which catalyst comprises depositing silver, a promoting amount of alkali metal, a promoting amount of rhenium and, optionally, a promoting amount of rhenium co-promoter selected from sulfur, molybdenum, tungsten, chromium and mixtures thereof, on a porous refractory support, at least partially drying the support, and thereafter depositing a promoting amount of nickel on the support.
