Coal-based Activated Carbon: Brief Introduction and Applications
1. Brief Introduction
Coal-based activated carbon is a high-performance porous adsorbent made from anthracite, bituminous coal or lignite. It is processed through crushing, mixing, molding, high-temperature carbonization (300-600℃) and activation (steam physical activation or chemical activation), forming a well-developed pore structure and large specific surface area.
As a cost-effective product, it has advantages of high mechanical strength, good wear resistance, stable adsorption and easy regeneration. Available in granular, columnar or powdered forms, its specifications can be customized, making it widely used in industrial and daily scenarios.
2. Application Fields
2.1 Water Treatment
It is used in drinking water purification (adsorbing residual chlorine, organic pollutants, odors and chroma) and industrial wastewater treatment (treating printing and dyeing, papermaking, chemical wastewater to remove dyes, heavy metals and toxic organics).
2.2 Flue Gas Purification
Applied in thermal power plants, steel plants, etc., it removes SO₂, NOₓ, VOCs and dust from flue gas, achieving desulfurization, denitrification and deodorization to meet environmental emission standards.
2.3 Food and Beverage Industry
Used for decolorization, deodorization and purification in sugar, edible oil, wine and beverage production, improving product purity and taste.
2.4 Chemical Industry
It serves as adsorbent for organic solvent recovery (benzene, toluene, etc.) and catalyst carrier in chemical reactions, reducing waste and improving reaction efficiency.
2.5 Other Fields
Also used in gas separation, gold extraction, indoor/industrial air purification and aquaculture sewage treatment.
