摘要 |
A rapid synthesis method of a small-crystal-grain ZSM-5 molecular sieve, the method comprising: preparing a mixed silicon-aluminum glue solution, placing the solution in a crystallization kettle for low-temperature nucleation, enabling high-temperature crystallization growth of the solution, and obtaining a crystallization product, namely, a small-crystal-grain ZSM-5 molecular sieve, the nucleation temperature being 60-120°C, nucleation time being 1-3 hours, a crystallization growth temperature being 150—170°C, and crystallization growth time being 1-3 hours. The method is easy to operate, and has a short operation time, thus being able to complete within 6 hours; in addition, the product has uniform grain sizes, is in a mono-dispersed state, and has a high crystallization degree to a submicron degree. |
