Abstract:
A catalyst for the production of ethylene oxide in high efficiency and high selectivity, as well as stably for a long period of time is provided.A catalyst for the production of ethylene oxide comprising silver and a reaction promoter supported on a porous carrier comprising α-alumina as a main component, characterized in that a relative standard deviation of silver supporting rate of each particle of the catalyst is 0.001 or more and 0.1 or less.
