| titleOfInvention | A kind of alpha-alumina supports, corresponding silver catalyst and application |
| abstract | The invention discloses a kind of application of alpha-alumina supports and corresponding silver catalyst, their preparation method and the silver catalyst in epoxidation reaction of olefines production epoxide.Using siliceous water aluminium oxide as raw material, fluoride and alkaline earth metal compound as auxiliary agent, wherein element silicon quality is (with SiO in a water aluminium oxide 2 Meter) Zhan Yishui quality of alumina 0.05~10.0%, by kneading, molding, drying, roasting, prepare alpha-alumina supports, again with the carrier of the solution dipping preparation containing organic amine, silver compound, tungsten auxiliary agent, rhenium auxiliary agent, alkali metal promoter, silver catalyst is made by leaching, activation.The silver catalyst is in alkene epoxidation production epoxide reaction, the selectivity and stability that can especially do well in ethylene epoxidizing production reacting ethylene oxide, and selectivity promotion speed is fast. |
