Difference Between Impregnated Activated Carbon and Ordinary Activated Carbon

Impregnated activated carbon is made from granular/cylindrical/powdered activated carbon with high adsorption performance, impregnated with alkaline solutions such as potassium hydroxide and sodium hydroxide, and then refined by high-temperature drying. This kind of activated carbon is widely used to remove organic gases and vapors from air or other gas streams, such as hydrogen sulfide, sulfur dioxide, etc. Impregnated activated carbon has a large specific surface area and suitable pore structure, can withstand high temperature and high pressure, is not easily broken, is easy to regenerate, and has a long service life. It not only performs well in liquid phase adsorption and air purification, but also plays an important role in the purification, separation and refining of chemical raw material gases, pharmaceutical industry gases, carbon dioxide gas for beverages, hydrogen, chlorine and other gases. In addition, impregnated activated carbon is also widely used in fields such as hydrogen sulfide gas removal and oxidation gas adsorption in PTA devices. Compared with ordinary activated carbon, impregnated activated carbon has significant differences in terms of material, production process, scope of use and performance. Impregnated activated carbon is obtained by special impregnation treatment of ordinary activated carbon. Its raw materials are the same as ordinary...

Why Choose Kelin Activated Carbon for Water Purification?

Water purification activated carbon is a type of activated carbon used to purify water. The use of activated carbon filter adsorption method to purify water is to use its porous solid surface to adsorb and remove organic matter or toxic substances in the water, so that the water can be purified. Research shows that activated carbon has strong adsorption capacity for organic matter in the molecular weight range of 500-1000. Advantages of Kelin Activated Carbon for Water Purification: Kelin series activated charcoal for water purification mostly uses coconut shell as raw material and is refined and processed using advanced production technology. The product has the advantages of developed pore structure, high strength, low impurity content, appropriate particle size, low resistance, and easy regeneration. It has an excellent effect on water purification. It can not only remove odor and odor, but also improve the purity of water. It also has a high removal rate for various impurities in water, such as chlorine, phenol, arsenic, lead, cyanide, pesticides and other harmful substances. It can be widely used to fill various large, medium and small water purifiers.   Application of Activated Charcoal in Water Purification:   Water purification activated carbon is generally columnar particles...

Why Need to Choose Water Washed Activated Carbon?

The main purpose of water-washed activated carbon products is to remove surface impurities, improve pore structure and improve adsorption performance. ‌ Activated carbon will carry some impurities and soluble substances during the production process, which may affect its adsorption performance. Through water washing treatment, these impurities can be effectively removed, thereby improving the purity and adsorption performance of activated carbon‌. In addition, water washing can also reduce the ash content of activated carbon, improve its pore structure, make it more uniform and orderly, thereby improving its adsorption efficiency and life‌.   The specific steps and precautions for water-washed activated carbon include: first, avoid using fresh tap water, because the chlorine in tap water will reduce the adsorption life of activated carbon; second, the impurities can be helped to fall off by stirring or shaking during the water washing process; finally, it should be thoroughly rinsed after water washing to prevent impurities from remaining‌. Through water washing treatment, the adsorption performance and service life of activated carbon can be significantly improved, making it more suitable for various complex environmental conditions. For example, in water treatment systems, water-washed activated carbon can better remove harmful substances such as organic matter, microorganisms and residual...

The Difference Between Biochar and Activated Carbon

Although biochar and activated carbon are both composed of carbon elements and have adsorption capabilities, they have significant differences in structure and application fields. And today we will mainly talk about it. Difference Between Biochar and Activated Carbon 1. Composition and structure: Biochar is mainly composed of carbon elements, with loose and porous characteristics. Its pores are unevenly distributed, with both macropores and micropores and mesopores, and the specific surface area is usually within 400 square meters per gram. Activated carbon is also composed of carbon elements, but it is looser than ordinary charcoal and has stronger adsorption capacity. Activated carbon is mainly microporous, with a specific surface area of more than 1000 square meters per gram. Even activated carbon prepared using seaweed as raw material can have a specific surface area of about 2000. 2. Application areas: Biochar is widely used in agriculture, industry, environment, new energy and other fields. For example, in the agricultural field, biochar can improve the water holding capacity and nutrient supply of the soil, increase microbial activity, and help increase crop yields. In the environmental field, biochar, as an excellent adsorption material, can remove pollutants in the environment. Activated carbon has excellent adsorption properties...

How To Use Activated Carbon In Water Treatment

Activated carbon is a specially treated carbon with numerous tiny pores and a huge surface area, with a surface area of 500-1500 square meters per gram of activated carbon. Activated carbon has strong physical adsorption and chemical adsorption functions, and also has a detoxification effect. The detoxification function is to use its huge area to adsorb the poison in the air of the activated carbon, thereby preventing the absorption of the poison. At the same time, activated carbon can bind to a variety of chemical substances, thereby preventing the absorption of these substances. Because activated carbon has high requirements for water pretreatment and the price of activated carbon is expensive, in wastewater treatment, activated carbon is mainly used to remove trace pollutants in wastewater, which has achieved the purpose of deep purification. (1) Activated carbon treatment of chromium-containing wastewater Chromium is a metal raw material with a large amount in electroplating, and hexavalent chromium exists in different forms in wastewater with different pH. Activated carbon has a very developed microporous structure and high specific surface area, and has strong physical adsorption capacity, which can effectively adsorb Cr(VI) in wastewater. There are a large number of oxygen-containing groups on the surface...
