PROBLEM TO BE SOLVED: To provide an ethylene oxide production catalyst in which stability of catalyst performance is improved and good reaction characteristics are obtained over a long period from the initial reaction stage without accompanying an extreme increase in the reaction temperature.SOLUTION: Provided is an ethylene oxide production catalyst comprising a carrier, silver and rhenium, in which the carrier contains therein silicon in an amount of 0.01 wt.% to 1.0 wt.% in terms of SiO, and the carrier has, in a pore distribution measured by mercury press-in method, at least two peaks having a maximal value of log differential pore volume of 0.2 ml/g or more in a range of pore diameter of 0.01 μm to 100 μm, where at least one of the peaks is present in a range of 0.5 μm to 3.0 μm.SELECTED DRAWING: Figure 1 |
