| titleOfInvention | Method for preparing ZSM-22 molecular sieve by using seed crystal synthesis method |
| abstract | The invention relates to a preparation method of a molecular sieve, and provides a method for preparing ZSM-22 molecular sieve by using a seed crystal synthesis method. The method comprises the following steps of: uniformly mixing deionized water with aluminum sulfate; adding alkali sources into a mixture; adding tetraethoxysilane under stirring; continuously stirring until the solution is uniform to form silicon-aluminum gel; adding ZSM-22 molecular sieve crystal seed to stir; putting the mixture into a reaction kettle for crystallization reaction; and filtering and drying a product to obtain ZSM-22 molecular sieve raw powder. By using the preparation method, the application of organic template agent is eliminated, the crystallization time is shortened, the crystallization temperature is reduced, and the industrial application is facilitated; the product keeps good crystallization degree and purity and high catalytic reaction activity; the unnecessary loss during production is reduced; the product has a potential application value on some important catalytic reaction; and inorganic raw materials used in production is environmentally-friendly and low in cost. |
