Coconut shell activated carbon is commonly used in gas-phase adsorption, which usually allows the airflow to be adsorbed through the activated carbon layer. According to the different states of the activated carbon layer in the adsorption device, there are several types of adsorption layers: fixed layer, moving layer, and flowing layer. However, in small adsorbers such as refrigerators and deodorizers in cars, adsorption relies on gas convection and diffusion. In addition to granular activated carbon, activated carbon fibers and formed products are also increasingly being widely used in gas-phase adsorption.
2. The air in instrument rooms, air conditioning rooms, basements, and underwater facilities often contains body odor, smoking odor, cooking odor, oil, organic and inorganic sulfides, corrosive components, etc. due to external pollution or the influence of human activities in enclosed environments, causing corrosion of precision instruments or affecting human health. Activated carbon can be used for purification to remove impurities.
3. Coconut shell activated carbon can be used in the gases emitted from chemical plants, leather factories, paint factories, and engineering projects that use various organic solvents. It contains various organic solvents, inorganic and organic sulfides, hydrocarbons, chlorine gas, oil, mercury, and other harmful components to the environment. Activated carbon can be used for adsorption before discharge. The gases emitted from atomic energy facilities contain radioactive substances such as krypton, xenon, and iodine, which must be adsorbed clean with activated carbon before being discharged. The smoke generated from 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 many uses of coconut shell activated carbon for refining gases, such as gas masks, cigarette filters, refrigerator deodorizers, car exhaust treatment devices, etc., which utilize the adsorption performance of activated carbon to remove toxic components, harmful components to the human body, or odorous components from the gas.
