Embodiment 1
[0037] The carrier material prepared according to the method provided by the present invention.
[0038] With 150g modified hydrogen type Y molecular sieve (SiO 2 / Al 2 o 3 =5.1 (molecular ratio, the same below), the unit cell constant is Relative crystallinity is 90%) add 2 liters of distilled water, stir beating, form slurry (a), add 4000g solid aluminum sulfate to 7.5 liters of distilled water, heat simultaneously and stir until dissolving, obtain aluminum sulfate solution (b), Al 2 o 3 The concentration is about 4g / 100ml. Dilute the concentrated ammonia water into about 10% dilute ammonia water (c) by adding appropriate amount of distilled water. 10 liters of distilled water is added in the strong water glass of 4.8 liters of a kind of industrial grade modulus 3.0, obtains dilute water glass solution (d). Take a 15-liter steel reaction tank, add 2 liters of distilled water in the tank and stir and heat to 70°C, open the valves of the containers containing aluminum s...
Embodiment 2
[0040] 150g of modified hydrogen form β (SiO 2 / Al 2 o 3 =28, the unit cell constant is Relative crystallinity is 87%) Molecular sieve is added into 2 liters of distilled water, stirs beating, forms slurry (a), 4000g solid aluminum sulfate is added into 7.5 liters of distilled water, heats simultaneously and stirs until dissolving, obtains aluminum sulfate solution (b), al 2 o 3 The concentration is about 4g / 100ml. Dilute the concentrated ammonia water into about 10% dilute ammonia water (c) by adding appropriate amount of distilled water. 10 liters of distilled water is added in the strong water glass of 4.8 liters of a kind of industrial grade modulus 3.0, obtains dilute water glass solution (d). Take a 15-liter steel reaction tank, add 2 liters of distilled water in the tank and stir and heat to 70°C, open the valves of the containers containing aluminum sulfate and ammonia water respectively, and slowly add (a) into the reaction tank, press Prepare 750g of silicon-...
Embodiment 3
[0042] With 150g modified hydrogen type Y molecular sieve (SiO 2 / Al 2 o 3 =5.1, the unit cell constant is Relative crystallinity is 90%) add 2 liters of distilled water, stir beating, form slurry (a), add 4000g solid aluminum sulfate to 7.5 liters of distilled water, heat simultaneously and stir until dissolving, obtain aluminum sulfate solution (b), Al 2 o 3 The concentration is about 4g / 100ml. Mix (a) and (b) into (b'). Dilute the concentrated ammonia water into about 10% dilute ammonia water (c) by adding appropriate amount of distilled water. 10 liters of distilled water is added in the strong water glass of 4.8 liters of a kind of industrial grade modulus 3.0, obtains dilute water glass solution (d). Get a 15-liter steel reaction tank, add 2 liters of distilled water in the tank and stir and heat to 70 ° C, open the valves of the containers that respectively store aluminum sulfate (containing molecular sieve slurry) and ammonia water, and prepare 750 g of silicon-...
