preparation example Construction

[0050] In step (1), "providing a mesoporous molecular sieve material with a three-dimensional cubic pore structure" can be directly weighed or selected a product of a mesoporous molecular sieve material with a three-dimensional cubic pore structure, or can be prepared with a three-dimensional cubic pore structure. Mesoporous molecular sieve materials. The preparation method of the mesoporous molecular sieve material with a three-dimensional cubic channel structure can be implemented according to a conventional method, for example, the preparation method can include: preparing a filter cake of a mesoporous molecular sieve material with a three-dimensional cubic channel structure according to the above method, and then The obtained filter cake is dried, and the templating agent in the product obtained after drying is removed. The conditions for removing the template agent may include: a temperature of 300-600° C. and a time of 10-80 hours.

Embodiment 1

[0092] This example is used to illustrate the spherical chlorite mesoporous composite material and supported catalyst of the present invention and their preparation methods.

[0093] (1) Preparation of spherical chlorite mesoporous composites

[0094] Dissolve 6g (0.001mol) of triblock copolymer surfactant P123 in 10ml of hydrochloric acid aqueous solution with a pH value of 4 and 220ml of deionized aqueous solution, stir for 4h until P123 dissolves to form a transparent solution, and then add it to the transparent solution Add 6g (0.08mol) of n-butanol and stir for 1h, then place it in a water bath at 40°C, slowly add 12.9g (0.062mol) of tetraethyl orthosilicate into the solution, and keep the temperature at about 40°C. Stir for 24 hours at a pH value of 4.5, then hydrothermally treat at 100°C for 24 hours, then filter and wash with deionized water for 4 times, and then suction filter to obtain filter cake X1 of mesoporous molecular sieve material with three-dimensional cubic...

Embodiment 2

[0113] This example is used to illustrate the spherical chlorite mesoporous composite material and supported catalyst of the present invention and their preparation methods.

[0114] The spherical chlorite mesoporous composite material and the supported catalyst were prepared according to the method of Example 1. The difference was that there was no spray drying step in the process of preparing the supported catalyst, but the benzenesulfonic acid was loaded on the surface only by impregnation. On the spherical chlorite mesoporous composite material, the supported catalyst Cat-2 was prepared.
