Embodiment 1
[0018] Synthesis of ZSM-5 molecular sieves with MFI topology.
[0019] First prepare colloidal seeds, 710.3g H 2 O, 13.8g NaOH and 117.0g TPAOH (20% solution) solution are fully dissolved and mixed until uniform, and then 158.9g silicic acid is gradually added to the above solution under stirring, fully shaken at room temperature for 1h, and aged at 100°C 16h; 867.8g H 2 O, 8.8g NaOH and 10.3g sodium aluminate are fully mixed and dissolved, 113.1g silicic acid is gradually added to the above mixed solution under full stirring and shaken violently for 1h, and 50g of the prepared colloidal seed crystals are added to the above mixed solution Shake for 1 h, then transfer the material to a stainless steel reactor. After crystallization at 180°C for 40h, the crystalline product was filtered, washed and dried. The crystalline product obtained by XRD powder diffraction analysis is ZSM-5 molecular sieve, and its silicon-aluminum ratio is 12-13.5.
