Embodiment 1
[0123] (1) Measure 12mL water glass solution (purchased from Sinopec Catalyst Changling Branch, SiO 2 Content is 280g / L, modulus is 3.26) dissolved in deionized water to prepare 95mL water glass dilute solution. 100.0g of pseudoboehmite powder (purchased from Sinopec Catalyst Changling Branch, dry basis content of 69.5% by weight), 4.0g of methylcellulose (purchased from Zhejiang Haishen Chemical Co., Ltd.), 3.0g of Sesame powder Mix well with 95mL of the above water glass dilute solution. The resulting mixture is fed into an extruder and extruded to obtain a wet strip. The extruded wet strip was placed in an oven and dried at a temperature of 200° C. for 6 hours to obtain a carrier. The radial crushing strength, water absorption and δ value of the obtained carrier were measured, and the results are listed in Table 1.
[0124] (2) Dissolve 0.47g basic nickel carbonate (NiO content is 51% by weight), 1.2g molybdenum oxide and 0.23g phosphoric acid in water to prepare a 60mL ...
Embodiment 2
[0138] (1) In a 2L reaction tank, add 2000mL of aluminum sulfate solution and sodium metaaluminate solution (Al 2 o 3 content of 200g / L, caustic coefficient of 1.58) for precipitation reaction, the reaction temperature is 50°C, the pH value is 6.0, and the reaction residence time is 15 minutes; the obtained slurry is filtered with a vacuum filter. Add 20L of deionized water (at a temperature of 40±5°C) to the filter cake to rinse the filter cake for about 60 minutes. Add the washed filter cake into 1.5L deionized water and stir to form a slurry, then pump the slurry into the spray dryer for drying, control the outlet temperature of the spray dryer within the range of 100-110°C, and the material drying time is 2 minutes to obtain amorphous hydrated alumina, wherein, Al 2 o 3 The content is 63% by weight, and it is determined to be amorphous by XRD analysis.
[0139] (2) Weigh 50.0g of alkaline silica sol (purchased from Beijing Hongxing Guangsha Chemical Building Materials ...
Embodiment 3
[0142] (1) Weigh 5.0 g of acidic silica sol (purchased from Beijing Zhongxi Yuanda Technology Co., Ltd., SiO 2 The content is 30% by weight, Na 2 O<0.006% by weight, pH 2-6), dissolved in deionized water with stirring to prepare 95 mL of acidic silica sol aqueous solution. 60.0g of pseudo-boehmite (purchased from Sinopec Catalyst Changling Branch, with a dry basis content of 69.5% by weight), 40.0g of gibbsite (purchased from Guangxi Pingguo Aluminum Company, with a dry basis content of 64.5% by weight %), 1.0g methylcellulose (purchased from Zhejiang Haishen Chemical Co., Ltd.), 2.0g hydroxypropyl methylcellulose (purchased from Zhejiang Haishen Chemical Co., Ltd.), 3.0g scallop powder and 95mL of the above acid silicon The aqueous sol solution was stirred evenly. The resulting mixture is fed into an extruder and extruded to obtain a wet strip. The obtained wet strip was placed in an oven and dried at a temperature of 200° C. for 12 hours to obtain a carrier. The radial c...
