Pillared layered saponite-containing catalyst carrier and preparation method and application thereof, hydroisomerizing cracking catalyst and application of catalyst

[0024] As previously mentioned, the present invention provides a kind of preparation method that contains layer saponite catalyst support, and this method comprises:

[0025] (1) Grinding the first slurry containing hydrogen-type phyllophyllite to reduce the particle size of hydrogen-type phyllophyllite to increase the number of effective acid sites on the surface, and mixing the ground first slurry with an alumina source And evenly dispersed to obtain the second slurry;

[0026] (2) After mixing the second slurry and an adhesive, molding is performed to obtain a layered pillarite catalyst carrier.

[0027] The method for preparing a catalyst carrier containing layered saponite in the present invention is to grind the first slurry containing hydrogen-type layered saponite, mix the ground first slurry with an alumina source and uniformly disperse to obtain a second slurry, so that The finally obtained layered pillared saponite catalyst carrier has the advantages of increasing the

[0029] According to a preferred embodiment of the present invention, preferably the solid content of the first slurry is 0.5-50wt%, preferably 10-35wt%, and the method further includes: mixing the second slurry and / or the ground first slurry One slurry is dewatered so that the solid content of the second slurry is 1-50 wt%, preferably 10-30 wt%.

[0030]According to the preparation method of the present invention, the purpose of dewatering the second slurry and / or the ground first slurry is to increase the solid content of the second slurry so that subsequent molding can proceed smoothly, wherein the water removal process There is no special requirement, for the present invention, preferably, the step of dewatering the second slurry includes: centrifuging the second slurry, removing the supernatant, and then homogeneously dispersing and drying.

[0031] According to the present invention, preferably, the step of removing water from the ground first slurry includes: drying the

[0104] Dissolve 99.5g of sodium metasilicate nonahydrate, 4.8g of sodium hydroxide, and 82.68g of sodium carbonate in 500g of water to make lye, then take 60.9g of magnesium chloride hexahydrate and 12.1g of aluminum chloride hexahydrate in 50g of water to make Salt solution, slowly drop the salt solution into the above alkaline solution at 60°C to obtain an initial gel with a synthetic saponite layer charge of 1.0 (pH 10.58), then continue to age for 30 minutes, put it into a 1L autoclave, and heat it at 300°C Crystallized for 48h. The obtained product was centrifuged and washed with deionized water until it was close to neutral to obtain a stesterite wet cake, which was denoted as Na-MgSP (moisture content: 80wt%).
