Coal Based Activated Carbon For Desulfurization and Denitrification
Activated carbon is porous carbon material.Due to its highly developed porous structure and huge specific surface area,activated carbon has very strong adsorption capacity, Its pores include micropores mesopores and macropores, diameter has >2nm,20-200nm,>200nm respectively.
There are many oxygen containing functional groups on the surface of activated carbon, Activated carbon can also be impregnated with chemical substance to produce impregnated activated carbon.Thus,it is not only used as an excellent adsorbent but also used as a catalyst and catalyst carrier and widely used in industrial production agriculture environmental protection national defence industry water purification . decolorization of pharmaceutical intermediates and raw material intermediates air purification.etc
This granular activated carbon It is obtained by carbonization of high quality natural coal under isolated air conditions at a high temperature of 600-900 ℃, followed by oxidation activation with air, carbon dioxide, water vapor, or a mixture of the three gases at 400-900 ℃.
The production process of activated carbon
Activated carbon, is a specially treated carbon that heats organic raw materials (rice husks, coal, wood, etc.) in the absence of air to reduce non-carbon components (this process is called carbonization), and then Reacting with the gas, the surface is corroded to produce a microporous structure (this process is called activation).
Because the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, resulting in numerous small pores on the surface of activated carbon. The diameter of micropores on the surface of activated carbon is mostly between 2-50nm. Even a small amount of activated carbon has a huge surface area. The surface area per gram of activated carbon is 500-1500m2. Almost all applications of activated carbon are based on this characteristic of activated carbon.
Application areas
Our activated carbon and ultraviolet technologies help purify water, air, food and beverages, pharmaceuticals and more. We develop and manufacture innovative solutions in collaboration with our customers.
Treating Diesel Fuel on the Boat The K.I.S.S. Rule Activated charcoal filters reduce water density levels by trapping water molecules in the charcoal's molecular surface and never releasing them back as natural filtration occurs. Carbon filters that have an oxidation treatment block any remaining organic contamination and bacteria.
In addition, Activated carbon can be used in methane and hydrogen storage, air purification, capacitive deionization, supercapacitive swing adsorption, solvent recovery, decaffeination, gold purification, metal extraction, water purification, medicine, sewage treatment, air filters in respirators, filters in compressed air, teeth whitening, production of hydrogen chloride, edible electronics,and many other applications.

How to choose high quality activated carbon
Choosing high-quality activated carbon requires considering several key factors. Activated carbon is widely used in various applications, such as water purification, air filtration, gas adsorption, and more.
Here are some important factors to consider when selecting high-quality coal activated carbon:
1.Source of coal :
The quality of the activated carbon is heavily influenced by the source of the natural coal . Ensure that the raw material used are of high quality and free from contaminants, as this can impact the final product's effectiveness.
2.Activation Method:
The activation process greatly affects the characteristics of the activated carbon. There are two common activation methods: physical activation (e.g., steam activation) and chemical activation. Steam activation is preferred as it produces high-quality activated carbon with larger surface areas and excellent adsorption properties.
3.Surface Area and Pore Structure:
The efficiency of activated carbon depends on its surface area and pore structure. Higher surface area and a well-developed pore structure (micropores and mesopores) contribute to better adsorption capacity. The surface area is usually measured in square meters per gram (m²/g).
4.Adsorption Capacity:
The adsorption capacity of activated carbon determines its ability to remove impurities. It is measured by parameters like iodine number (mg/g) and methylene blue (mg/g). Higher values indicate better adsorption capabilities.
5.Particle Size:
The particle size of activated carbon can impact its performance in specific applications. Finer particles generally have more surface area and are more suitable for liquid phase applications, while coarser particles are often used in gas phase applications.
6.Ash Content:
Low ash content is essential for high-quality activated carbon. Excess ash can lead to undesirable side reactions and reduce the active sites available for adsorption.
7. PH and Moisture Content:
The pH and moisture content can influence the chemical properties and stability of activated carbon. Ensure that the pH is within an appropriate range, and the moisture content is minimized for better storage and handling.
8.Certification and Testing:
Look for activated carbon that meets international standards, such as ASTM (American Society for Testing and Materials) or ISO (International Organization for Standardization). Manufacturers may provide test reports showing key parameters like surface area, adsorption capacity, and impurity levels.
9.Application-Specific Considerations:
Different applications have specific requirements. Ensure the activated carbon you choose is well-suited for your intended use, such as drinking water treatment, air purification.
10.Supplier Reputation:
Choose a reputable supplier with a track record of providing high-quality activated carbon. Customer reviews and testimonials can give insights into the supplier's reliability and product quality.
Remember to thoroughly research and compare different products and suppliers before making a purchase. By considering these factors, you can increase the likelihood of selecting high-quality activated carbon for your specific needs.
