    摘要： Disclosed is a catalyst for ethylene oxide production which is used for producing ethylene oxide from ethylene. This catalyst is composed of at least silver (Ag), caesium (Cs), rhenium (Re) and a carrier, and improved especially in selectivity. Specifically disclosed is a catalyst for ethylene oxide production, which is used for producing ethylene oxide from ethylene and composed of at least silver (Ag), caesium (Cs), rhenium (Re) and a carrier. If necessary, an alkali metal is loaded onto the carrier as a pretreatment, and then Ag, Cs and Re are loaded onto the carrier, thereby obtaining the catalyst. The carrier has a specific surface area of 0.6-3.0 m2/g, and a weight ratio between the silicon (Si) content and the sodium (Na) content in terms of SiO2/Na2O of 2-50, The Re content (based the carrier) is 170-600 ppm per 1 m2/g or the specific surface area of the carrier, and the molar ratio Cs/Re is 0.3-19.
