Method for preparing honeycomb activated carbon

Stop carbonization of raw materialsCarbonization is also called pyrolysis, which is heating the original material under the condition of isolating air, and the normal temperature is below 600?. Sometimes the original materials are first dissolved in inorganic salts and then carbonized.After the raw material of activated carbon is carbonized, it will synthesize and release gases such as water vapor, carbon monoxide, carbon dioxide and hydrogen; the raw material is synthesized into fragments and re-separated into a stable structure. These fragments may be composed of some microcrystals.Microcrystals are composed of two or more sheets of carbon atoms arranged in a hexagonal lattice structure. But there is no fixed crystal form for accumulation. honeycomb activated carbon The size of the microcrystal is related to the composition and structure of the original material, and is affected by the carbonization temperature, and roughly increases with the increase of the carbonization temperature. After carbonization, some remaining hydrocarbons are attached to the atoms on the border of the microcrystals.Stop activation of semi-waste activated carbonActivation is to heat the carbonized materials under the action of an oxidant to consume activated carbon products. When the temperature of the oxidation process is 800-900°C, steam or carbon dioxide is generally used as the oxidant; when the oxidation temperature is below 600°C, air is generally used as the oxidant.www.wyactivatedcarbon.comAs for the role played by the activation process, only a general understanding is needed. In the activation process, the hydrocarbons adsorbed during carbonization are burned off, and the hydrocarbon atoms on the edges of the original voids are burned, which has the effect of expanding the pores and burning through the pores. Activation makes the activated carbon into a good porous structure, and the crystal flakes after carbonization and activation.
