  • Ethylene oxide production using fixed moderator concentration
    Patent number: 7803957
    Abstract: A method for controlling ethylene oxidation uses ethylene and oxygen, in conjunction with a silver based catalyst, a moderator and a co-moderator, to form ethylene oxide. When controlling the ethylene oxidation reaction, the moderator concentration is maintained constant within a comparatively narrow operative concentration range and the co-moderator concentration is varied within a comparatively wider operative concentration range, to optimize a catalyst property such as the catalyst activity and/or the catalyst selectivity.
    Type: Grant
    Filed: September 11, 2007
    Date of Patent: September 28, 2010
    Assignee: SD Lizenzverwertungsgesellschaft mbH & Co. KG
