Product Overview
DC is a high-quality coal-based granular activated carbon manufactured from select bituminous coal through carbonization and steam activation. Designed for liquid-phase purification, it effectively decolorizes and refines chemical process streams, sugar syrups, and pharmaceutical intermediates. Available in two size grades (DC 830 and DC 1240), DC delivers balanced adsorption of color bodies, organic impurities, and colloidal contaminants with excellent durability in fixed-bed service.

Key Application Areas
- Sugar & Syrup Decolorization: Removes caramel pigments, polyphenols, and colloids from cane and beet sugar syrups, ensuring consistent crystallization yield and premium product color grade.
- Glycerine Purification: Adsorbs color, odor, and trace organics from crude and biodiesel-derived glycerine, enabling upgrade to pharmaceutical and food-grade specifications.
- Pharmaceutical Manufacturing: Purifies active pharmaceutical ingredients, intermediates, and fermentation broths by removing color bodies and process residues under pharmacopeial standards.
- Chemical Processing: Refines organic and inorganic acid streams, solvent recovery products, and specialty chemicals by adsorbing impurities and oxidation byproducts.
- Nutraceutical & Beverage Processing: Clarifies botanical extracts, protein isolates, and beverage streams without adsorbing beneficial active compounds, preserving nutritional value.
Key Advantage
- Balanced Pore Architecture: The combination of micropores and mesopores handles both small molecules and large color bodies, providing versatile purification across diverse liquid streams.
- High Mechanical Strength: >90% crush strength ensures minimal fines generation during backwash and extended filter runs, reducing operational downtime and media replacement costs.
- Rapid Adsorption Kinetics: Optimized particle size and pore distribution enable fast equilibrium in batch and continuous systems, improving production throughput.
- Regenerable Performance: Thermal reactivation restores adsorption capacity for multiple cycles, offering lifecycle cost advantages in high-volume sugar and chemical processing.
