CATALYST FOR ETHYLENE OXIDE PRODUCTION AND METHOD FOR PRODUCING ETHYLENE OXIDE

摘要

Disclosed is a catalyst for ethylene oxide production, which has excellent selectivity and catalyst life (durability). Specifically disclosed is a catalyst for ethylene oxide production, in which a catalyst component containing silver (Ag), cesium (Cs), rhenium (Re) and tungsten (W) or molybdenum (Mo) is supported by a carrier that has a specific surface area of 0.5-1.3 m2/g, an Si content (in terms of SiO2) of 0.1-5.0% by mass and an Na content (in terms of Na2O) of 0.05-1.0% by mass.
