Silver catalyst for the oxidation of ethylene oxide

摘要

The invention relates to a silver catalyst for the partial oxidation of ethylene with molecular oxygen in the gas phase to form ethylene oxide and a process for preparing ethylene oxide using this catalyst. The catalyst is superior to comparable catalysts of the prior art through an increased selectivity (at high activity) and/or a more favorable ageing behavior. The process for preparing ethylene oxide is distinguished by improved economics.
