1. Coconut shell particle 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 gas emissions 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. It can be adsorbed with activated carbon and then discharged. 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., all of which utilize the excellent adsorption performance of activated carbon to remove toxic components, harmful components to the human body, or odorous components from the gas. For example, by adding 100-120ng of activated carbon to the filter tip of a cigarette, a significant portion of harmful components to the human body can be removed from the smoke.
5. Desulfurization activated carbon: used as a carrier for gasoline desulfurization (deodorization) catalysts in catalytic units of oil refineries.
6. Vinylon catalyst activated carbon: used in the chemical industry as a catalyst carrier, such as as as a carrier for vinyl acetate catalyst.
7. Monosodium glutamate refined activated carbon: used for decolorization and refining of mother liquor in the production process of monosodium glutamate, and can also be used for decolorization and refining of fine chemical products.
8. Activated carbon for cigarette filter tips: used in the cigarette industry to remove toxic and harmful substances such as tar and nicotine in cigarette filters.
9. Citric acid specific activated carbon: used for decolorization, refining, and deodorization of various acids such as citric acid, amino acids, and cysteine.
10. Special activated carbon for direct drinking water treatment: Activated carbon is used for deep water purification in household direct drinking water, water treatment in waterworks, and bottled water production.
