الكربون المنشط المستخرج من الفحم

Coal-based activated carbon is a high-throughput, industrially proven sorbent material produced from carefully chosen coal raw materials—mainly bituminous coal, brown coal, and anthracite—by a two-stage process of carbonation and activation. In the process of manufacture, the original coal is carbonized at elevated temperatures to eliminate the volatile matter, followed by activation of vapor or CO₂ to create a wide and highly interconnected interior pore structure, which is optimized for large-scale absorption.

Coal-based activated carbon, one of the world’s largest production and consumption sources, has attracted wide attention due to its extraordinary versatility, excellent mechanical properties, and a wide range of pores across micropores, mesopores, and macropores. This multiscale pore structure enables it to absorb various pollutants at the same time—from the tiny amounts of dissolved organic matter and chlorine in the wastewater to the VOCs and the industries in the air cleaning system. Coal-based activated carbon is especially suitable for large-volume, continuous flow industry processes for which durability and throughput are key operating priorities.
