Crushed Coal Activated Carbon: The Cost-Effective Adsorbent for Water & Air Purification

1. What is Crushed Coal Activated Carbon?

Crushed coal activated carbon is an **irregularly shaped adsorbent** produced by **crushing and screening** 

high-quality coal-based carbon into specific particle sizes (typically **0.5–4 mm**). It offers **high adsorption capacity, cost efficiency, and versatility** in liquid and gas-phase applications.  

Key Features:* 

✔ **High surface area** – Iodine value **800–1100 mg/g**  

✔ **Multiple size options** – 4×8, 8×30, 12×40 mesh available  

✔ **Cost-effective** – Cheaper than extruded or pelletized carbon  

✔ **Wide applications** – Water treatment, air purification, chemical processing  

### **Technical Specifications:**
