Honeycomb activated carbon is manufactured by compressing high-quality coal, wood chips, coconut shell powder, and other raw materials into a black, non-toxic, odorless structure using a small amount of binder at high temperatures. Its porous honeycomb structure features abundant pores, providing a large specific surface area, low fluid resistance, and strong adsorption capacity. Widely used in industries such as petrochemicals, chemicals, energy, construction materials, printing, automotive, electronics, pharmaceuticals, food processing, aquaculture, and environmental protection, it serves multiple purposes including solvent recovery, coal carrier systems, gas phase adsorption, water purification, and exhaust purification for indoor/outdoor public spaces. Key pollutants effectively removed include nitrogen oxides, carbon tetrachloride, chlorine, benzene, formaldehyde, acetone, ethylbenzene acetate, methanol, acetic acid, styrene, phosgene, malodorous gas, and other acidic and alkaline gases.
