| titleOfInvention | Preparation method, catalyst and the application of silver catalyst for alkene epoxidation |
| abstract | The invention discloses a kind of preparation methods of silver catalyst for alkene epoxidation, the described method comprises the following steps: 1) providing alumina support；2) mixed solution of Ag-containing compound and organic amine is prepared, and impregnates the carrier；The solution for preparing rhenium-containing auxiliary agent, impregnates the carrier；3) mixture after the dipping in step 2) is separated by solid-liquid separation, obtains solid particle；4) solid particle in step 3) is dried, the drying carries out in the process for including at least two stages, and wherein the first stage is freeze-dried, and second stage carries out low temperature drying；5) solid particle after drying is activated, obtains the silver catalyst.The silver catalyst so prepared shows improved activity and selectivity when being used for ethylene epoxy ethane.The invention further relates to catalyst prepared in accordance with the present invention and its applications in ethylene production ethylene oxide. |
