Coal-based activated carbon JZ-ACN appears as black extruded pellets and is made from high-quality, low-ash coal through activation and refinement. It features a well-developed pore structure, with a specific surface area of 600-900 m²/g and an iodine adsorption value of up to 600-900%. With strong adsorption capacity for low-polarity gas molecules, it is effective in gas purification, including the removal of organic gases, toxic gases, and other contaminants. It is commonly used for pre-treatment in nitrogen generators and can also deoxygenate inert gases such as carbon monoxide and carbon dioxide, efficiently removing oil and other impurities from raw gases.
