| titleOfInvention | Microsphere-type MFI topology structure all-silicon-1 molecular sieve catalyst containing trace rare earth ions and preparation method thereof by spray molding |
| abstract | The invention relates to the field of all-silicon-1 molecular sieves, and discloses a microsphere-type MFI topology-structured all-silicon-1 molecular sieve catalyst containing trace rare earth ions and a spray-forming preparation method thereof. The catalyst comprises 70-95 wt wt on a dry basis % of all-silicon-1 molecular sieves containing extremely small amounts of rare earth ions, and 5 to 30wt% of a binder; the particle size of the catalyst is 20 to 400 (m, and the wear index K is less than 5; the all-silicon-1 molecular sieves are The BET specific surface area of the catalyst is 400‑500 m2 /g, and the weight ratio of silica to rare earth ions is (10000‑200000): 1. The catalyst has a low wear index and is used in the fluidized bed process for cyclohexanone oxime The gas phase Beckmann rearrangement reaction can effectively improve the technical economy of the new process. |
