    摘要: The invention is directed to a catalyst for the epoxidation of an olefin to an olefin oxide, the catalyst comprising a support having at least two pore size distributions, each pore size distribution possessing a different mean pore size and a different pore size of maximum concentration, the catalyst further comprising a catalytically effective amount of silver, a promoting amount of rhenium, and a promoting amount of one or more alkali metals, wherein the at least two pore size distributions are within a pore size range of about 0.01 μm to about 50 μm. The invention is also directed to a process for the oxidation of an olefin to an olefin oxide using the above-described catalyst.

    摘要: The invention is directed to a catalyst useful in the epoxidation of an olefin to an olefin oxide, the catalyst comprising a support having a multimodal pore size distribution comprising a first and a second distribution of pore sizes wherein each distribution of pore sizes possesses a different mean pore size and a different pore size of maximum concentration, the support having a catalytically effective amount of silver, a promoting amount of rhenium, and cesium in an amount up to, but not exceeding 700 ppm disposed thereon. The invention is also directed to methods for using the catalyst for the commercial production of an olefin oxide from olefin and oxygen-containing feed gases.
