摘要： An improved carrier for an ethylene epoxidation catalyst is provided. The carrier includes an alumina component containing a first portion of alumina particles having a particle size of, or greater than, 3 μm and up to 6 μm, and a second portion of alumina particles having a particle size of, or less than, 2 μm. An improved catalyst containing the above-described carrier, as well as an improved process for the epoxidation of ethylene using the catalyst are also provided.

摘要： An improved carrier for an ethylene epoxidation catalyst is provided. The carrier includes an alumina component containing a first portion of alumina particles having a mean primary particle size of, or greater than, 2 m and up to 6 m, and a second portion of alumina particles having a particle size less than 2 m. An improved catalyst containing the above-described carrier, as well as an improved process for the epoxidation of ethylene using the catalyst are also provided.
