PROBLEM TO BE SOLVED: To provide a silver catalyst which is excellent in catalytic activity, selectivity and catalyst life and can produce ethylene oxide with high selectivity over a long period of time, a method for producing the same, and a method for producing ethylene oxide using the silver catalyst I will provide a. SOLUTION: A carrier mainly composed of α-alumina contains silica and a metal or a compound of at least one element selected from the elements of groups Ib and IIb of the periodic table, for example, silver oxide. To make a catalyst for producing ethylene oxide. The carrier comprises at least α-alumina, a silicon compound, an organic binder, b, and after mixing a compound of at least one element selected from elements of group IIb, 1,000 to 1,800 It is obtained by firing at ℃. |
