ABSTRACT:
This invention relates to a supported silver catalyst for the manufacture of ethylene oxide prepared by a process comprising impregnating a porous catalyst support with a solvent containing a silver salt and treating the impregnated support to effect deposition of silver on the support surface. Following silver deposition, the support is impregnated with a liquid containing a compound of at least one metal promoter dissolved in an organic solvent in which water is soluble at ambient temperature in an amount no greater than about 50 wt. % based on the weight of the water-solvent solution. The impregnated support is then treated to effect deposition of the promoter. There is also described herein a process of making such catalyst and a process for producing ethylene oxide.
