| titleOfInvention | Rotation molding preparation method and application of microsphere all-silicon molecular sieve catalyst with MFI topology structure containing trace rare earth ions |
| abstract | The invention relates to the field of all-silicon molecular sieves, and discloses a rotational molding preparation method of a microsphere all-silicon molecular sieve catalyst with an MFI topology structure containing trace rare earth ions and an application thereof. The preparation method includes: a. , an organic template agent and water are mixed to obtain a colloidal mixture; b. The colloidal mixture is subjected to staged hydrothermal crystallization, and the obtained crystallized product is subjected to membrane filtration and washing, and dried to obtain an all-silicon molecular sieve containing trace rare earth ions; c. The silicon molecular sieve is pulverized, mixed with a binder, and turned into a microsphere all-silicon molecular sieve catalyst; d. calcined, contacted with an alkaline buffer solution of nitrogen compounds, washed, filtered, and dried to obtain a finished product. The catalyst has a low attrition index and can be used for the gas-phase Beckmann rearrangement of cyclohexanone oxime in a fluidized bed process to improve the technical economy of the new process. |
