Coconut shell activated carbon is a type of activated carbon produced from the shells of coconuts. It is widely used for its high adsorption capacity, It can be used in multiple industries such as water quality purification and ultra pure water filtration,gold extraction in gold mines and air filtration and purification; Here are some key points about coconut shell activated carbon:
How to make coconut shell activated carbon?
Carbonization is the process of converting organic materials into carbon by heating them in the absence of oxygen. This process is used to produce coconut shells charcoal. Load the crushed coconut shells into a carbonization furnace or kiln.Heat the shells at temperatures ranging from 400°C to 800°C in an oxygen-free environment. This can be done using a traditional pit kiln or a more advanced carbonization machine.Maintain the temperature and conditions to facilitate the breakdown of the organic material into carbon and volatile substances.
The activation process is to use activated gases (such as water vapor, flue gas) to undergo an oxidation-reduction reaction with C, eroding the surface of the carbonized material, while removing tar like substances and uncarbonized materials, resulting in the development of the fine pore structure of the carbonized material. This process includes the diffusion of activators from the gas phase to the outer surface of the carbonized material, the adsorption of activators by the inner and outer surfaces of the carbonized material, and the desorption of intermediate and reaction products generated by gasification reactions. Through this process, the specific surface area of activated carbon increases and the pores are developed, thereby improving its adsorption performance.
After activation, the activated carbon is crushed, screened and processed into appropriate particle size for packaging and transportation to the warehouse.
