Coconut shell activated carbon is primarily used for deodorization and drinking water filtration, and is an emerging water purification material. What exactly is coconut shell activated carbon? What should be noted when using it?
What is coconut shell activated carbon?
Coconut shell activated carbon is a porous carbonized material with abundant pore structures, boasting excellent adsorption properties. Its adsorption effect is a combination of physical and chemical adsorption forces, with a vibrant color. Besides the primary carbon content, it also contains trace amounts of hydrogen, nitrogen, and oxygen. Its structure, resembling a hexagonal shape within irregular hexagonal patterns, determines its large volume and high surface area, with each gram of activated carbon having a surface area equivalent to over 1,000 square meters. Made from coconut shells, this activated carbon is refined through physical methods, featuring a large specific surface area, high strength, uniform particle size, well-developed pore structure, and strong adsorption capabilities. It is produced from coconut, walnut, apricot, and peach shells through a series of production processes, resulting in black granular appearance. Its advantages include a well-developed pore structure, a large specific surface area, strong adsorption properties, low capillary pressure, stable chemical properties, and ease of regeneration. It is suitable for deep purification, dechlorination, decolorization, deodorization, and gold refining in high-purity drinking water, industrial water, and wastewater treatment.
What to note when using coconut shell activated carbon?
1. When transporting coconut shell activated carbon, avoid mixing it with hard materials and prevent stepping on it to avoid breakage. This is to ensure the filtration effect is not compromised, thereby affecting water quality.
2. When storing coconut shell activated carbon, it should not be soaked in water. Soaking it in water will cause water to enter the pores, thereby rendering it ineffective. This is something to be aware of.
3. Avoid contact with tar substances as tar can easily block the pores of the activated carbon bed, thereby losing its adsorption effect. It is advisable to have a tar removal device to ensure the normal use of coconut shell activated carbon.
4. Coconut shell activated carbon must be fireproofed during transportation, as it is highly flammable and can easily spontaneous combustion under high temperatures. Therefore, attention must be paid to the following points.
Coconut shell activated carbon is a black, irregularly shaped activated carbon, processed through a series of production techniques. It boasts excellent wear resistance, well-developed porosity, high adsorption capacity, high strength, easy regeneration, and cost-effectiveness.
What are the uses of coconut shell activated carbon?
1. Coconut shell activated carbon is widely used in daily life, industry, liquid phase adsorption, water purification, and gas phase adsorption.
2. Coconut shell activated carbon also has extensive applications in the food processing industry.
3. Coconut shell activated carbon is used for purifying edible oils or biodiesel, derived from the high-pressure cracking and acetic transfer of natural glycerin.
4. Refined glycerin, as a food additive, prevents food from cracking or the phase change caused by cracking, thereby improving the softness of food and the chewiness of candies.
5. Coconut shell activated carbon can be used in the refining of sucrose, suitable for decolorizing syrup to crystallize into white sugar.
6. Coconut shell activated carbon can also be used to enhance the biochemical conversion efficiency during fermentation processes. For the purification of lactate and gluc酸盐 products, coconut shell activated carbon meets stringent purification requirements.
Coconut shell activated carbon is widely used in water treatment, with a history of several decades. Since the advent of home water purifiers, coconut shell activated carbon has been used as a filter core, serving as an important adsorption material in household water purification systems. The coconut shell activated carbon has a 5 times higher adsorption capacity for organic gases than regular activated carbon, after being carbonized through high-temperature activation. It is primarily used for purifying drinking water, air, and industrial wastewater, as well as for decolorization and deodorization. It can also be applied in the desulfurization of thiols in the oil refining industry, with the saturation period greatly depending on the usage environment. This is because in environments containing moisture or recycled gases, the adsorption rate of coconut shell activated carbon for organic solvents generally decreases.
Coconut shell activated carbon process is an intriguing process related to adsorption and biological decomposition. As is well-known, the permeation phenomenon occurring in fixed bed activated carbon towers, adsorption is an unstable separation operation, while biological decomposition is a stable reaction operation after the acclimatization period. Therefore, analyzing the phenomena produced in the reactor can be considered as falling under the category of separation operations accompanying the reaction.
But in reality, due to the presence of multi-component systems, this phenomenon is much more complex. The quality of water treated with coconut shell activated carbon is also hard to predict, among many other issues yet to be clarified. Therefore, coconut shell activated carbon is the future trend in activated carbon development.
