The application of coconut shell activated carbon in waste gas treatment?

  1. Granular activated carbon is often used in gas phase adsorption, usually by letting air flow through the activated carbon layer for adsorption. According to the state of the activated carbon layer in the adsorption device, the adsorption layer has a fixed layer, a moving layer and a fluid layer. However, small adsorbers such as electric ice frost and deodorizers in automobiles rely on gas convection and diffusion for adsorption. In addition to granular activated carbon, activated carbon fibers and activated carbon moldings are also increasingly widely used in gas phase adsorption.
  2. The air in instrument rooms, air-conditioning rooms, basements and subsea facilities often contains body odor, smoking odor, cooking odor, oil, organic and inorganic sulfides, and corrosive components due to external pollution or the influence of crowd activities in a closed environment. Etc., causing corrosion of precision instruments or affecting human health. Activated carbon can be used for purification to remove impurities.
  3. The gas discharged from chemical plants, leather factories, paint factories, and projects that use various organic solvents contains various organic solvents, inorganic and organic sulfides, hydrocarbons, chlorine, oil, mercury, and other environmentally harmful gases. The components can be adsorbed by activated carbon before being discharged. The gas discharged from nuclear power facilities contains radioactive krypton, xenon, iodine and other substances, which must be absorbed cleanly with activated carbon before being discharged. The flue gas generated by the combustion of coal and heavy oil contains sulfur dioxide and nitrogen oxides, which are harmful components that pollute the atmosphere and form acid rain. They can also be adsorbed and removed by activated carbon.
  4. There are still many use cases of coconut shell activated carbon used to refine gas, such as gas masks, cigarette filters, refrigerator deodorizers, automobile exhaust gas treatment devices, etc., all of which use the excellent adsorption performance of activated carbon to remove toxic components in the gas, which is harmful to the human body. The ingredients or smelly ingredients are removed. For example, after adding 100~120ng activated carbon to the cigarette filter, as shown in Table 3-6-2, a large part of the harmful components in the smoke can be removed
