| titleOfInvention | A kind of MFI topology structure silicon molecular sieve containing trace rare earth ions and preparation method thereof |
| abstract | The invention relates to the field of silicon molecular sieves, and discloses an MFI topology silicon molecular sieve containing trace rare earth ions and a preparation method thereof. The silicon molecular sieve has a BET specific surface area of 400-500 m 2 /g and a particle size of 0.15-0.25 microns , the mass ratio of silicon dioxide to rare earth ions is (10000-200000): 1, and the preparation method includes: a, mixing a silicon source, a rare earth ion source, an organic template agent and water to obtain a colloidal mixture; b, mixing step a The colloidal mixture obtained in the two-stage variable temperature hydrothermal crystallization. By adopting the method of the invention, a near-neutral silicon molecular sieve with high crystallinity, fine particles and extremely small amount of rare earth metal ions can be obtained, and the content of rare earth ions is in the range of 5-100ppm. The conversion rate of cyclohexanone oxime can prolong the life of the catalyst and improve the economy of the new process technology of gas phase rearrangement. |
