| titleOfInvention | A kind of silver catalyst for ethylene epoxidation to produce ethylene oxide, preparation method and application thereof |
| abstract | The invention belongs to the field of industrial catalysts, and relates to a silver catalyst for producing ethylene oxide by epoxidizing ethylene and a preparation method and application thereof. The method includes the following steps: (1) obtaining a silver amine immersion solution I and a silver amine immersion solution II, wherein the silver amine immersion solution I contains silver compound, ethanolamine, ethylenediamine and water; the silver amine immersion solution II contains silver compound, ethanolamine, ethylenediamine, alkali metal auxiliary and water; the silver amine impregnation solution I and/or silver amine impregnation solution II also contain organic rhenium auxiliary agent; (2) impregnating the alumina carrier with silver amine impregnation solution I and draining; (3) thermally decomposing the sample obtained in step (2) to prepare a sample of impregnated silver catalyst; (4) impregnating the sample of one-time impregnated silver catalyst with silver amine impregnation solution II and draining; (5) ) thermally decompose the sample obtained in step (4). The silver catalyst of the invention has high activity and selectivity, and is especially suitable for the reaction of producing ethylene oxide by epoxidizing ethylene. |
