Abstract

PROBLEM There is provided a catalyst for producing ethylene oxide which is superior in catalytic selectivity and catalytic life (durability). SOLUTION There is provided a catalyst for producing ethylene oxide having a catalyst component supported on a carrier, wherein the carrier has specific surface area of 0.5 to 1.3 m/g, Si content (SiOequivalent) of 0.1 to 5.0% by mass and Na content (NaO equivalent) of 0.05 to 1.0% by mass, and the catalyst component is silver (Ag), cesium (Cs), rhenium (Re) and tungsten (W) or molybdenum (Mo).
