  • Silver catalyst for the oxidation of ethylene to ethylene oxide and process for preparing ethylene oxide
    Patent number: 5734068
    Abstract: 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.
    Type: Grant
    Filed: March 25, 1997
    Date of Patent: March 31, 1998
    Assignee: Huels Aktiengesellschaft
