preparation example Construction
[0031] The invention provides a method for preparing a three-dimensional space network structure activated carbon fiber skeleton, comprising the following steps:
[0032] Firstly, the wood fibers loaded or not loaded with activator and activated catalyst are bonded by polymer binder with or without activator and activated catalyst to obtain a three-dimensional space bonded by polymer binder. Non-fabric prefabricated body with network structure, wood fibers are distributed in three-dimensional and multi-directional, interweaved and cross-connected.
[0033] Then, the non-woven prefabricated body is subjected to carbonization and activation treatment to obtain an activated carbon fiber skeleton with a three-dimensional network structure loaded or not loaded with a catalyst.
[0034] In the preparation method of activated carbon fiber skeleton with three-dimensional space network structure of the present invention, the bonding between fibers in the aforementioned three-dimensiona...

[0051] Immerse coconut palm silk with a length of 30mm-250mm and a material-to-liquid ratio of 1:3-5 in ZnCl at 60°C 2 Immerse in the solution for 8 hours, the solution concentration is 50-57 degrees Baume, and the pH value is 1.0-3.5. After centrifugal drying, dry to a moisture content of 15%-20%, and the loaded ZnCl 2 Activator of coconut palm silk; the ZnCl 2 Added to natural latex aqueous solution to obtain a concentration of 6% ZnCl 2 Latex binder; Prepared coconut palm fiber is transported to cyclone separator, by free fall, obtains the fiber layer that thickness is 30mm; According to coconut palm fiber and natural latex dry matter weight ratio, be the glue consumption of 1:1, The prepared natural latex is evenly sprayed on the fiber layer, and the coconut palm fiber is bonded together, and then dried to obtain a coconut palm fiber mat with a moisture content of less than 20%. Bond 10 pieces of 30mm fiber felt to obtain a coconut palm felt with a thickness of 300mm; pu...

[0056] Dry the oil palm silk with a length of 30mm-250mm to a moisture content of 15%-20%; melt the asphalt to obtain an asphalt binder. The prepared oil palm silk is transported to the cyclone separator, and a fiber layer with a thickness of 20mm is obtained by free falling; according to the ratio of oil palm silk and asphalt mass ratio of 1:1.5, the prepared asphalt binder Spray evenly on the fiber layer to bond the fiber bundles into one. Put the oil palm flakes with a thickness of 20mm under the press, press statically for 10 seconds at a temperature of 120°C and a pressure of 5Mpa, and cut to obtain a density of 0.3g / cm 3 oil palm silk non-fabric preforms.
[0057] Put the oil palm silk non-fabric prefabricated body into the kiln and heat it at a heating rate of 10°C / min, heat it to 450°C-600°C and keep it warm for 90 minutes for carbonization; then continue heating at a heating rate of 15°C / min, and heat it to 800°C ℃~950℃, continuously inject superheated steam at 300℃...
