About Impregnated Activated Carbon
Our Impregnated Activated Carbon is enhanced with specific chemical impregnants for targeted removal of contaminants that standard carbon cannot effectively capture. Available with KOH, NaOH, KS, sulfur, and other treatments.
Engineered for H2S removal, mercury capture, acid gas treatment, and specialized industrial applications requiring enhanced adsorption performance.
- Targeted contaminant removal
- Multiple impregnant options available
- Effective for H2S and mercury removal
- Custom formulations available
Technical Specifications
Our impregnated activated carbon is available on coconut shell, coal-based, and wood-based base carbons. The choice of base material and impregnant type depends on your specific target contaminant and operating conditions.
Base Carbon Material Options
| Base Material | Characteristics | Best Applications |
|---|---|---|
| Coconut Shell | High microporosity, superior hardness (>=98%), low ash (<=3%) | High-purity gas treatment, nuclear iodine capture, pharmaceutical |
| Coal-Based | Balanced pores, cost-effective, good hardness (>=92%) | H2S removal from biogas, flue gas treatment, odor control |
| Wood-Based | High mesoporosity, low ash (<=5%), fast kinetics | Catalyst support, specialized chemical reactions |
Impregnant Types & Target Contaminants
| Impregnant | Loading Level | Target Contaminants |
|---|---|---|
| KOH / NaOH | 5-15% | H2S, mercaptans, organic acids, odor compounds |

Standard activated carbon relies on physical adsorption. Impregnated carbon adds a chemical reaction mechanism: the impregnant reacts with specific target contaminants, providing much higher removal capacity for those compounds than physical adsorption alone.
KOH-impregnated carbon is the most common choice for H2S removal. For higher capacity, we also offer NaOH or specialty alkaline-impregnated grades. Our engineers can recommend the best option based on your gas composition and operating conditions.
Standard orders are ready to ship within 7-15 business days. Popular grades like KOH-impregnated pellet carbon are kept in stock for faster turnaround.
In most cases, impregnated carbon is used as a disposable media because the chemical impregnant is consumed during the adsorption process. However, some grades can be partially regenerated. Contact us to discuss your specific application.
