    摘要： 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.

    摘要： 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 hard 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. Following the hard strip, the catalyst is optionally re-optimized. Surprisingly, it has been found that the selectivity of the catalyst following the hard strip may be substantially higher than the selectivity prior to the hard strip.

    摘要： The present invention relates to a process for improving the selectivity of an EO process utilizing a highly selective EO catalyst. In particular, the present invention is an improvement in the initial operation of a process for manufacturing ethylene oxide by contacting ethylene, oxygen, a chloride moderator and a hydrocarbon co-moderator with a high selectivity silver-containing catalyst at a concentration of carbon dioxide of less than about 2 mole percent, wherein the initial operating temperature is determined by optimization of such initial operating temperature at a level higher than the normal low initial operating temperature that is typically selected to obtain a longer operating cycle.
