Process for preparing silver-supported catalyst for the production of ethylene oxide

摘要: An improved process for preparing a silver-supported catalyst use in the production of ethylene oxide by catalytic vapor phase oxidation with molecular oxygen, which comprises impregnating porous inorganic carrier solution silver compound containing reducing compound, subjecting impregnated product to treatment at 50° 200° C. disperse and deposit metallic on external surface internal surfaces its pores, washing water, lower alcohol or both, drying washed temperature 150° C., dried promoter, evaporating liquid ingredients.
