Catalytic
Activated Carbon
Self-catalyzing H₂S oxidation without chemical impregnation. Regenerable for lower long-term operating costs.
⚡ Quick Answer
Catalytic activated carbon has surface chemistry engineered to oxidize H₂S and chloramines through catalytic reaction rather than physical adsorption alone, delivering H₂S capacity 0.20–0.40 g/cm³ — 2–4× higher than standard carbon. Iodine number 600–900 mg/g, CTC 40–60%, hardness > 95%, steam-regenerable. Available as pellet (Φ4 mm) and granular (4×8, 8×30) in coal-based or coconut-shell base.

Product Overview
Catalytic activated carbon represents the next generation of H₂S removal technology. Through a proprietary activation process, we modify the carbon surface to create catalytic sites that promote the oxidation of H₂S to elemental sulfur — without any chemical impregnation.
The key advantage: catalytic carbon can be thermally regenerated 3-5 times, dramatically reducing replacement costs. It is the preferred choice for continuous operations where long-term economics matter more than initial price.
Catalytic vs Impregnated Comparison
| Feature | Impregnated | Catalytic |
|---|---|---|
| Mechanism | Chemical reaction | Catalytic oxidation |
| Regenerable | No (chemicals consumed) | Yes (3-5 cycles) |
| H₂S Capacity | 0.15-0.30 g/cm³ | 0.20-0.40 g/cm³ |
| Long-term Cost | Higher (replace only) | Lower (regenerate) |
| Best For | High concentration, batch | Continuous, moderate conc. |
