Yihang Activated carbon pellets for air purification is made of high quality anthracite coal, wood or coconut shell. Through the depth of activation and unique aperture adjustment process, the activated carbon has a lot of holes, and the size of the hole slightly bigger than the toxic gases, specific surface area is more than 1300 square flat/g, for benzene, methyl , ammonia and other toxic or harmful gases have highly efficient adsorption ability, It can effectively remove gaseous pollutants and harmful odor substances in indoor air, and then achieve the purpose of reducing pollution and purifying air. It can also be used for disinfection and filtration of gas masks and protective equipment. Activated Carbon Pellets features:  Less impurities, high quality, developed space, strong adsorption capacity.

Coconut shell activated carbon is a kind of activated carbon with better air filtration effect. The coconut shell activated carbon of Yihang brand used for air purification and electric power industry has high-efficiency air purification function. Yihang desulfurizated activated carbon has a very high H2S removal capacity. It can also be used for Garbage burning and Solvent recovery. Technical Principle Coconut shell activated carbon used for air purification has the function of combining physical adsorption and chemical decomposition to decompose harmful gases such as formaldehyde, ammonia, benzene, cigarettes, oil fume and various peculiar smells in the air, especially carcinogenic aromatic substances. Coconut shell activated carbon used for air purification has extremely strong adsorption capacity. It is a commonly used adsorbent, catalyst or catalyst carrier, and it is easy to fully contact with harmful gases in the air. The coconut shell activated carbon used for air purification uses its own pore adsorption to suck harmful gas molecules into the pores to purify the air In the electric power industry, the coconut shell activated carbon used by the Yihang brand in the electric power industry can purify boiler flue gas. There are generally three types of coconut shell activated carbon used in the electric power industry: 1) Influent treatment: Impurities in the water are treated once. 2) Effluent treatment: some substances will be produced after being added, which is not allowed to be discharged, and it must be treated again at this time.

Yihang honeycomb activated carbon for aquarium water purification treatment with coal, coconut shell as raw material, its two times after high temperature heating firing, making its hardness is greater, water softening, stronger adsorption, low ash, easy to wash, water quality is good, strong acid and alkali resistance. Used for waste water treatment, water purification, organic solvent recovery and adsorption. Technical principle Honeycomb activated carbon has a strong physical adsorption and chemical adsorption role, can remove some organic compound adsorption and achieve effect, use of this principle, we can quickly and effectively remove the harmful substances in the aquarium water quality, smell, and pigment and so on, make water quality directly and quickly improve. Honeycomb activated carbon for aquarium water treatment is an activated carbon used to purify water. Using activated carbon filter material adsorption method to purify water is to use its porous solid surface, adsorption removal of pollutants or toxic substances in water, so that water purification.
