CATALYST FOR PREPARING ETHYLENE OXIDE AND METHOD FOR PREPARATION OF ETHYLENE OXIDE

摘要

PROBLEM TO BE SOLVED: To provide a catalyst for preparing ethylene oxide with high selectivity. SOLUTION: This catalyst for preparing ethylene oxide by oxidizing ethylene is obtained by carrying at least one of alkali metals and at least one of the 5th group elements with an atomic number of at least 41 on a porous carrier as a pretreatment, and then carrying silver and at least one of alkali metals.
