Coconut Shell Columnar Activated Carbon
Columnar activated carbon is made from high-quality coal, coconut shell, and sawdust through a series of production processes. The appearance is black cylindrical particles, widely used in gas treatment, sewage treatment, desulfurization and denitrification, solvent recovery, nitrogen generation machines, air separation equipment, paint spraying workshops and other fields.
Columnar activated carbon has a good adsorption effect on volatile organic compounds in water, which can achieve a removal rate of 25%~65% for various volatile organic compounds in water. Comparing the adsorption patterns of various organic compounds with different molecular weights, it can be seen that for volatile organic compounds, the larger the molecular weight, the higher their removal rate. This is similar to the adsorption law of phenol and cationic light yellow, that is, for small molecule organic matter in water, the larger the molecular weight, the easier it is to be adsorbed by activated carbon.

Application Areas :
(1) Sewage Disposal
Activated carbon for sewage treatment is made from high-quality coal through processes such as crushing, carbonization, activation, and refinement. The pore structure is reasonable and can effectively purify domestic and chemical wastewater.
(2)Fish Pond Filtration
Due to its strong adsorption capacity, well-developed pores, and low dust, coconut shell columnar activated carbon is widely used for water purification in fish ponds and tanks, filtering impurities and small substances in the water, making it convenient for recycling and harmless
(3) Solvent Recovery
This product uses high-quality coconut shell as raw material and is refined by physical activation method. It is black columnar, non-toxic and odorless, with well-developed pores and reasonable distribution of the three types of pores, and has strong adsorption capacity. It has a high adsorption capacity for most organic solvent vapors over a wide concentration range and is widely applicable for the recovery of organic solvents such as benzene, ether, xylene, ethanol, acetone, gasoline, chloroform, carbon tetrachloride, etc.
(4) Water Treatment
Columnar activated carbon is widely used for deep purification of drinking water, industrial water, and wastewater; Separation, purification, and purification of various gases; Organic solvent recovery; Sugar making, monosodium glutamate, medicine, alcohol, beverage decolorization, deodorization, refining; Precious metal extraction; Catalysts and catalyst carriers in the chemical industry.
Transportation: During the transportation process, activated carbon should be prevented from mixing with hard substances and should not be stepped on or stepped on to prevent the carbon particles from breaking and affecting the quality.
Storage: Storage should be stored in porous adsorbents, so during transportation, storage, and use, it is absolutely necessary to prevent water immersion. After water immersion, a large amount of water fills the active pores, making them ineffective.
Fire prevention: When storing or transporting activated carbon, it is necessary to prevent direct contact with the ignition source to prevent ignition. During the regeneration of activated carbon, oxygen should be avoided and the regeneration should be thorough. After regeneration, it must be cooled down to below 80 ℃ by steam, otherwise the temperature will be high and the activated carbon will spontaneously ignite when encountering oxygen.
