Biogas contains contaminants such as hydrogen sulfide (H₂S), siloxanes, VOCs, and moisture that can damage CHP engines, pipelines, and upgrading equipment. XingSen provides high-efficiency activated carbon for biogas purification, helping improve biomethane quality and protect downstream systems.
Our solutions are widely used in:
We supply impregnated activated carbon, pelletized activated carbon, and coal-based extruded activated carbon for various biogas treatment applications.
Across all the applications mentioned above—from landfill sites to agricultural digesters—Hydrogen Sulfide (H2S) remains the single most destructive contaminant. If not strictly controlled through proper biogas desulfurization, residual H2S reacts with moisture to form sulfuric acid, leading to severe pitting corrosion in CHP engines and irreversible poisoning of downstream upgrading membranes.
To tackle this critical industry challenge, Xingsen Carbon provides specialized solutions designed for both high-concentration H2S removal and ultra-clean biogas polishing.
Compared with biological desulfurization systems, activated carbon offers:
Activated carbon is commonly used as a polishing stage after biological desulfurization in biogas treatment systems.
XingSen impregnated activated carbon removes H₂S through catalytic and chemical adsorption. The porous structure captures sulfur compounds while impregnated chemicals react with H₂S to form stable sulfur salts.
Main products include:
Selecting the right activated carbon depends on:
For high sulfur applications, impregnated activated carbon is typically recommended. For siloxane-heavy gas streams, high CTC activated carbon provides better adsorption performance.
| Property | Siloxane Carbon | H₂S Removal Carbon |
|---|---|---|
| Product Type | Extruded Pellet Carbon | Impregnated Activated Carbon |
| Main Application | Siloxane & VOC Removal | High H₂S Removal |
| Pellet Size | 3–4 mm | 4 mm |
| CTC Adsorption | 55–60% | ≥50% |
| H₂S Capacity | Standard | 20–35 wt% |
| Hardness | ≥95% | ≥95% |
| Pressure Drop | Low | Low |
| Typical Use | Landfill & Biomethane Systems | Biogas Desulfurization |
Impregnated activated carbon is widely used for biogas desulfurization due to its high sulfur adsorption capacity and stable performance.
Yes. High CTC activated carbon is commonly used for D4 and D5 siloxane adsorption in landfill gas and wastewater biogas systems.
Replacement frequency depends on H₂S concentration, gas flow, humidity, and carbon grade.
Biological systems are suitable for bulk sulfur removal, while activated carbon provides high-efficiency polishing and stable final purification.
Applications include landfill gas treatment, wastewater treatment plants, agricultural digesters, and biomethane upgrading facilities.
