摘要： Silver based ethylene oxide catalysts having enhanced stability are disclosed. The enhanced stability silver based ethylene oxide catalysts include an alumina carrier which has been modified to include cavities on the surface of the carrier. The presence of the cavities on the surface of the modified carrier stops or at least impedes the motion of silver particles on the surface of the carrier during an epoxidation process. In particular, the cavities on the surface of the alumina carrier effectively trap and/or anchor silver particles and prevent them from further motion.

The enhanced stability is obtained in the present invention by providing a silver-based ethylene oxide catalyst that includes from 100 ppm to 1000 ppm of zinc, and from greater than 450 ppm to less than 800 ppm of cesium. Zinc and cesium are promoters that are introduced to a finished carrier either prior to, coincidentally with, or subsequent to the deposition of the silver. The silver-based ethylene oxide catalyst can be used in the epoxidation of ethylene to ethylene oxide.
