A carrier of a catalyst for producing ethylene oxide, which makes it possible to prepare a catalyst for producing ethylene oxide having excellent catalytic performance, a catalyst for producing ethylene oxide having excellent catalytic performance obtained using the carrier, and a method for producing ethylene oxide using the catalyst Is initiated.n n n A carrier obtained by adding an aluminum compound, a silicon compound, and an alkali metal compound to α-alumina having an alkali metal content of 1 to 70 mmol / kg (α-alumina), and then calcining, wherein the aluminum content of the carrier is 0 to 3 mol in terms of aluminum. A carrier having a / kg-carrier, a silicon compound content of 0.01-2 mol / kg-carrier in terms of silicon, and an alkali metal compound content of 0.01-2 mol / kg-carrier in terms of alkali metal is used as a carrier for the catalyst for producing ethylene oxide. |
