| titleOfInvention | Heteropolyacid ammonium salt catalyst and preparation method thereof |
| abstract | The invention discloses a heteropoly acid ammonium salt catalyst and a preparation method thereof, wherein the catalyst comprises an active component, an auxiliary agent and a carrier, the active component is heteropoly acid ammonium salt, the auxiliary agent is phosphorus, and the carrier is an alumina and silicon dioxide composite carrier. The preparation method of the heteropoly acid ammonium salt catalyst comprises the steps of firstly preparing a catalyst precursor, then modifying the catalyst precursor, and finally loading an active component. The catalyst of the invention has higher reaction activity and selectivity, and is particularly suitable for the reaction of preparing ethylene by dehydration with low-concentration ethanol aqueous solution as a raw material. |
