| titleOfInvention | Micropore-mesopore catalyst material and preparation method thereof |
| abstract | The invention provides a catalyst material and a production process thereof, particularly a micropore-mesopore catalyst material for acid catalyzed reactions such as alkylation, cracking, esterification and the like, and a preparation method thereof. Specifically, organic additives such as citric acid, oxalate, glucose and the like are self-assembled with zeolite directing agent, and a thermal orhydro-thermal treatment method is employed to assist the preparation of the micropore-mesopore catalyst material. Through reactant composition and reaction condition regulation, the micropore-mesopore catalyst materials with different porous channel structures and pore sizes are synthesized. The micropore-mesopore catalyst material has the following beneficial effects: the produced catalyst material has dense mesopores, and pore walls around the mesopores are provided with micropore zeolite structure units, and the catalyst material has good catalytic performance. The used method is simple and efficient and is free from environmental pollution, and the channel system and the pore wall acidity of the micropore-mesopore catalyst material are changed by regulating the addition amount of organic additives, the hydrothermal crystallization temperature and time of silicon-aluminum sol and the molar ratio of silicon-aluminum atoms. The organic additives are used for replacing expensive mesopore template so as to greatly reduce production cost and provide preconditions for large-range popularization and application. |
