  • Publication number: 20120149926
    Abstract: The present invention relates to a process for improving the overall selectivity of an EO process for converting ethylene to ethylene oxide utilizing a highly selective EO silver catalyst containing a rhenium promoter wherein following normal operation a chloride strip of the chloride on the surface of the catalyst is conducted in order to remove a portion of the chlorides on the surface of the catalyst. The chloride strip involves the addition of certain saturated hydrocarbons to the feed. Following the chloride strip, the catalyst is optionally re-optimized.

  • Patent number: 8084632
    Abstract: A method for enhancing the efficiency of a rhenium-promoted epoxidation catalyst is provided. Advantageously, the method may be carried out in situ, i.e., within the epoxidation process, and in fact, may be carried out during production of the desired epoxide. As such, a method for the epoxidation of alkylenes incorporating the efficiency-enhancing method is also provided, as is a method for using the alkylene oxides so produced for the production of 1,2-diols, 1,2-carbonates, 1,2-diol ethers, or alkanolamines.

  • Patent number: 8084659
    Abstract: Embodiments disclosed herein provide processes for upgrading the hexene stream to valuable end products, including ethers, high purity 1-hexene, and, alternatively, high purity isohexene. Hexene upgrading may be performed in embodiments disclosed herein by first removing isohexene from the admixture. The isohexene may undergo etherification with one or more alcohols, facilitating the separation of the isohexene (in the form of an ether) from the normal hexenes. Second, the normal hexenes may be isomerized to convert internal hexene olefins (2-hexenes and 3-hexenes) to the desired alpha olefin, 1-hexene. The 1-hexene may then be separated from unreacted components to yield a high purity 1-hexene product.
