[0030] Example 1
[0031] Graphene, pore former (ferric chloride) and adhesive (silica sol) are blended in a mass ratio of 1:1:1, and added to the solvent (acetone) (the mass ratio of solvent to solid mixture is 1 :1), mixing at 20°C for 8 hours. The resulting mixture is fed into a molding machine to obtain a strip product with a diameter of 1 mm and a length of 10 mm. The strip product was dried at 100°C for 24 hours. The pore former (ferric chloride) is dissolved and removed with water, filtered, washed with deionized water to neutrality, and dried at 100°C for 20 hours to obtain the final product (the mass fraction of carbon nanomaterial is 50%. The specific surface area of the adsorbent is 2000m 2 / g, the pore volume ratio of micropores, mesopores and macropores is 2:5:20).
[0032] The adsorbent product is loaded into the equipment, and the upper and lower ends are fixed with the perforated cover plates, so that the height change rate of the adsorbent bed volume during th...

[0033] Example 2
[0034] The carbon nanotubes, the pore former (ammonium carbonate and sodium nitrate, 50% by weight) and the binder (aluminum sol) are mixed in a mass ratio of 10:1:4, and added to the solvent (ethanol) (solvent) The mass ratio to the solid mixture is 5:1), and the mixture is mixed at 40°C for 3 hours. The formed mixture is fed into a molding machine to obtain a sheet product with a diameter of 10 mm and a thickness of 5 mm. The sheet product was dried at 100°C for 12 hours, the pore former (ammonium carbonate and sodium nitrate) was dissolved and removed with water, filtered, washed with deionized water to neutrality, and dried at 80°C for 4 hours to obtain The final product (the mass fraction of carbon nanomaterials is 70%. The specific surface area of the adsorbent is 100m2 / g, and the pore volume ratio of micropores, mesopores and macropores is 1:5:20).

[0036] Example 3
[0037] The carbon nanotubes and graphene (50% each by mass), pore former (calcium carbonate) and binder (PVDF) were mixed at a mass ratio of 10:4:1 at 240°C for 6 hours. The formed mixture is fed into a molding machine to obtain a tubular product with a length of 8 mm, an inner diameter of 2 mm, and an outer diameter of 5 mm. The tubular product was dried at 70°C for 24 hours. The pore-forming agent (calcium carbonate) was removed with hydrochloric acid, filtered, washed with deionized water to neutrality, and dried at 120°C for 1 hour to obtain the final product (the mass fraction of carbon nanomaterials was 90%. Adsorbent The specific surface area is 1200m 2 / g, the pore volume ratio of micropores, mesopores and macropores is 2:1:10).
[0038] The adsorbent product is loaded into the equipment, and the upper and lower ends are fixed with the perforated cover plates, so that the height change rate of the adsorbent bed volume during the adsorption and desorptio...
