| titleOfInvention | A kind of hierarchical porous molecular sieve material and its preparation method |
| abstract | The invention belongs to the technical field of catalyst preparation, and discloses a multi-level porous molecular sieve material and a preparation method, successively weighing aluminum sulfate octadecahydrate, sodium silicate nonahydrate, tetrapropylammonium bromide and ammonium fluoride into polytetrafluoroethylene Add deionized water to the vinyl fluoride reaction kettle; add concentrated sulfuric acid after stirring with a magnetic stirrer, continue stirring, and then carry out hydrothermal reaction; cool to room temperature, centrifuge, wash with deionized water, and dry to obtain a white powder solid. The material provided by the present invention has a multi-level pore structure; the synthetic method of the synthetic NaY molecular sieve microsphere material provided by the present invention does not need to add directing agent, crystal seed, template agent, and the synthetic process is simple and convenient, can shorten the synthetic cycle, reduce cost. |
