Example Embodiment
[0052] Example 1
[0053] Raw material: 35.1g aluminum sulfate solution
[0054] 70.7g water glass
[0055] 12.4g sulfuric acid solution
[0056] 98.7g H 2 O
[0057] 0.8g NaZSM-5
[0058] Experimental process: First, slowly add aluminum sulfate solution under stirring the water glass solution to form a gel, then add the sulfuric acid solution, add NaZSM-5 seed crystals during rapid stirring, and then vigorously stir it evenly. After stirring, add the mercerizing synthesized in Comparative Example 1 0.5g of zeolite seed crystals were then transferred into the reaction kettle, crystallized at 165°C for 48 hours, and dried in an oven at 100-110°C for 3 to 4 hours to obtain the raw powder of mixed crystal material, numbered K1.

[0059] Example 2
[0060] Raw material: 35.1g aluminum sulfate solution
[0061] 70.7g water glass
[0062] 12.4g sulfuric acid solution
[0063] 98.7g H 2 O
[0064] 0.8g NaZSM-5
[0065] Experimental process: First, slowly add aluminum sulfate solution under stirring the water glass solution to form a gel, then add the sulfuric acid solution, add NaZSM-5 seed crystals during rapid stirring, and then vigorously stir it evenly. After stirring, add the mercerizing synthesized in Comparative Example 1 Zeolite seed crystal 0.9g, then transferred into the reaction kettle, crystallized at 165°C for 48 hours, and dried in an oven at 100-110°C for 3 to 4 hours to obtain the raw powder of mixed crystal material, numbered K2.

[0066] Example 3
[0067] Raw material: 35.1g aluminum sulfate solution
[0068] 70.7g water glass
[0069] 12.4g sulfuric acid solution
[0070] 98.7g H 2 O
[0071] 0.8g NaZSM-5
[0072] Experimental process: first slowly add aluminum sulfate solution under stirring the water glass solution to form a gel, then add the sulfuric acid solution, add NaZSM-5 seed crystals during rapid stirring, and then vigorously stir it evenly, add the mercerized synthesized in Comparative Example 1 after stirring. 1.6 g of zeolite seed crystals were then transferred into the reaction kettle, crystallized at 165°C for 48 hours, and dried in an oven at 100-110°C for 3 to 4 hours to obtain the raw powder of mixed crystal material, numbered K3.
