Embodiment 1
[0028] Mix 40% silica sol, aluminum hydroxide, templating agent Q1, and water in a molar ratio of 1SiO 2 :0.05Al 2 O 3 :0.15Q1:80H 2 O mixed uniformly, the above mixture was transferred into a reaction kettle and crystallized at 170° C. for 120 hours. After the reaction was completed, after washing and drying, a layered molecular sieve was obtained. The related structure of Q1 is shown in Table 1.
Embodiment 2
[0030] Combine 40% silica sol, alumina, templating agent Q2, and water in a molar ratio of 1SiO 2 :0.5Q2:100H 2 O mixes evenly, and the above mixture is transferred into a reaction kettle for crystallization at 150° C. for 100 hours. After the reaction is completed, after washing and drying, a layered molecular sieve is obtained. The related structure of template Q2 is shown in Table 1.
Embodiment 3
[0032] Combine silica, alumina, template Q2, and water in a molar ratio of 1SiO 2 :0.01Al 2 O 3 :0.2Q2:100H 2 O mixed uniformly, the above mixture was transferred into a reaction kettle and crystallized at 150° C. for 120 hours. After the reaction was completed, after washing and drying, a layered molecular sieve was obtained. The related structure of template Q2 is shown in Table 1.
