Epoxidation of Ethene over Silver Catalysts Supported on Crystalline α-Alumina Carriers

摘要

The α-alumina carriers with homogeneous pore structure and high purity were prepared from primary α-alumina crystal particles. The mean pore diameter was controlled by changing the primary particle size. In ethene epoxidation, the carriers having the mean pore diameter of 0.7-1.0 μm resulted in very stable and valuable performances.
