Example Embodiment
[0032] Example 1:
[0033] 240g of aramid fiber with a diameter of about 10μm and a length of 1mm, 620g with a specific surface area of 600m 2 / g of carbon molecular sieve, 200g of 40% polyurethane emulsion, add to 1.2L of water, stir and mix, then transfer to high-speed disperser for dispersion to form a uniform mixed slurry;
[0034] (2) The mixed slurry is made into paper on a paper machine to form a paper-like material with a thickness of 0.3mm, which is then rolled into a cylindrical monolithic absorbent material, dried at 100°C for 8 hours, and vacuum activated at 130°C for 3 hours to form a whole Structural adsorbent.
[0035] Obtained structured adsorbent, Langmuir method N 2 The specific surface area is 400m 2 / g.
