  • Patent number: 9133149
    Abstract: A method of producing an alkylene oxide includes passing a reaction mixture comprising alkylene, oxygen and a gaseous chlorine-containing promoter species over a supported catalyst containing silver and a promoting amount of rhenium to undergo an epoxidation reaction at a first operating condition. The method further includes subsequently performing the epoxidation reaction at a preferred operating condition. The preferred operating condition is characterized by an efficiency of the epoxidation reaction toward the alkylene oxide where the efficiency is lower than that of a maximum efficiency achievable at an operating temperature corresponding to the preferred operating condition.
    Type: Grant

  • Patent number: 8987483
    Abstract: A method for starting-up a high efficiency alkylene oxide catalyst is described. A feed gas comprising an alkylene, oxygen, and at least one organic chloride is introduced to the catalyst. The molar ratio of oxygen to alkylene, reaction temperature, and overall chloriding effectiveness are adjusted to specified ranges of values within a specified catalyst aging period.
