CATALYST FOR ETHYLENE OXIDE PRODUCTION AND METHOD FOR PRODUCING ETHYLENE OXIDE

摘要

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 2 /g, Si content (SiO 2 equivalent) of 0.1 to 5.0 % by mass and Na content (Na 2 O 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).
