Kelin has focused on the production and sales of activated carbon for decades. We are familiar with the application and common sense of activated carbon.
In the brewing, bottling, and soft drink production processes, activated carbon is mainly used for decolorization, odor removal, taste improvement, and product stability enhancement.
The core requirements for activated carbon in automotive cabin air filters mainly focus on high adsorption performance, low air resistance, and compatibility with composite filtration structures.
For the confined environment of diving equipment, ordinary air-purifying carbon is often insufficient; specially treated "impregnated activated carbon" is required.
The treatment of radioactive gases from nuclear power plants requires differentiation between iodine-based and inert gases: radioactive iodine requires nuclear-grade impregnated activated carbon (TEDA/KI composite impregnated coconut shell base), while inert gases require high specific surface area coconut shell/fruit shell base extended bed activated carbon. Both must be virgin materials and comply with ASME AG-1/ASTM standards.
1. Understanding "Impregnated Activated Carbon" The activated carbon used in gas masks is not ordinary activated carbon, but impregnated activated carbon (also
In the beer and beverage industry, activated carbon is the last critical line of defense for maintaining the flavor of CO2. Its large surface area and selective adsorption capacity effectively capture and remove trace organic matter that causes off-flavors, ensuring the pure and odorless CO2 ultimately added to the product, thus protecting the consistency and high-quality flavor of the brand.
For industrial gas purification, there's no one-size-fits-all activated carbon. Pillared, honeycomb, and spherical activated carbons are the mainstream choices. Which one best suits your application depends primarily on the composition, concentration, and air volume of the gas being treated, as well as your purification process and objectives.
Mercury removal activated carbon is a type of activated carbon that has undergone a special chemical treatment. Chemicals such as sulfur, iodine, or chlorine (most commonly elemental sulfur or iodide) are loaded onto its surface. This allows it to react strongly with mercury vapor (Hg⁰) to form stable mercury compounds (such as mercury sulfide, HgS), effectively and selectively removing mercury from gas or liquid streams.
Potassium permanganate activated carbon is a composite purification material made by loading the strong oxidant potassium permanganate (KMnO₄) onto a high-surface-area carrier (such as activated carbon, alumina spheres, or zeolite) through a specialized process. Activated carbon is the most common carrier.
Under other similar conditions, the larger the specific surface area of activated carbon, the higher its dioxin adsorption capacity. However, the "effectiveness" of specific surface area is also strongly influenced by pore size distribution and surface chemistry.
Activated carbon can be determined to be saturated by observing bubbles, testing air quality, and comparing colors. Regular replacement and scientific regeneration are also essential.
Columnar activated carbon can be used directly to adsorb and recover low-concentration gaseous ammonia. However, for ammonia in ammonia solutions (especially aqueous solutions), the direct adsorption efficiency is very low and it usually needs to be chemically modified before it can be used efficiently.
We focus on the produce of various types of cylindrical, granular, powder and high level impregnated activated carbon.
