| titleOfInvention | Catalyst for preparing ethylbenzene by ethanol and benzene vapor phase alkylation and preparation and application thereof |
| abstract | The application discloses a preparation method of a molecular sieve catalyst, which comprises the following steps: obtaining ZSM-5 seed crystal gel solution; adding a mixture I containing a silicon source, an aluminum source, an alkali and water into the ZSM-5 seed crystal gel solution to obtain a mixture, and aging to obtain a solid gel; under the sealing condition, carrying out steam-assisted crystallization, roasting, ammonium ion exchange and roasting on the solid gel to obtain the nano ZSM-5 molecular sieve; and (3) carrying out steam treatment and phosphorus modification on the obtained nano ZSM-5 molecular sieve, and roasting to obtain the molecular sieve catalyst. The catalyst has the characteristics of uniform acid site distribution and high crystallinity, and the preparation process generates less wastewater, thereby facilitating the large-scale production; the catalyst has good hydrothermal stability in the alkylation reaction of ethanol and benzene, can still maintain high ethyl selectivity under the condition of lower benzene-alcohol ratio feeding, has low content of xylene impurities in the product, and has good industrial application prospect. |
