Embodiment 1
[0028] a SF 6 The preparation method of the adsorbent for derivation gas protection thereof comprises the following steps:
[0029] (1) Mix 1g of methyl cellulose with 9g of kaolin (SiO 2 and Al 2 o 3 The total content is greater than 99%) and fully mixed with 10ml of deionized water, and then granulated (with a particle size of 1 mm to 1.5 mm) to obtain a green body.
[0030] (2) Dry the green body at 110°C, then roast at 800°C for 1 hour, then age in 10mol / L NaOH solution for 4 hours (ageing temperature is 50°C), and then raise the temperature to 90°C After crystallization for 3 hours, the crystallized product was finally washed with deionized water until the pH was 7.5, and dried to obtain the final synthesized product as a support.
[0031] (3) The mass concentration is 8% Zn (NO 3 ) 2 The solution was mixed with the product synthesized in step (2) in equal volumes, then ultrasonically vibrated for 8 hours, then dried at 105° C. for 2 hours, and finally calcined at 6...
Embodiment 2
[0036] a SF 6 The preparation method of the adsorbent for derivation gas protection thereof comprises the following steps:
[0037] (1) Mix 1.5g of methyl cellulose with 9g of kaolin (SiO 2 and Al 2 o 3 The total content is greater than 99%), fully mixed with 10ml of deionized water, and then granulated and shaped (the particle size of the calcined body is 1mm-1.5mm) to obtain a green body.
[0038] (2) Dry the green body at 110°C, then calcinate at 750°C for 2h, then age in 8mol / L NaOH solution for 3h (aging temperature: 60°C), then raise the temperature to 95°C for 2h to crystallize, Finally, the crystalline product was washed with deionized water until the pH was 8.0, and dried to obtain the final synthesized product as a carrier.
[0039] (3) The concentration is 15% Zn (NO 3 ) 2 It was mixed with the product synthesized in step (2) in equal volume, then ultrasonically vibrated for 6 hours, then dried at 110°C for 2 hours, and finally calcined at 650°C for 3 hours to...
