SELECTIVE DEALUMINATION OF ZEOLITES |
| 摘要 |
This invention relates to a process for selective dealumination, particularly surface dealumination of zeolites by sequential ion-exchange and calcination. The process is selective in the sense that the aluminium atoms within the pore structure of the zeolite remain virtually intact. The surface dealuminated zeolites can be used, after loading with a gallium compound, as catalysts in hydrocarbon conversion reactions. |
