Biogas, which is the result of the anaerobic fermentation of organic matter, is primarily composed of methane (CH₄) and carbon dioxide (CO₂). However, it also contains impurities such as hydrogen sulfide (H₂S), siloxanes (organic silicon compounds), and other organic compounds that can negatively impact energy processes and infrastructure. Therefore, effective biogas purification is crucial before directing it for further use.
Activated carbon is widely recognized as the best solution for removing contaminants from biogas, such as H₂S, siloxanes, and other organic compounds (including VOCs). Thanks to its porous structure, activated carbon efficiently adsorbs these harmful substances, allowing for the safe and effective use of biogas. Additionally, biogas can undergo an upgrading process to transform it into a higher-purity biomethane.

Hydrogen Sulfide (H₂S) Removal: Hydrogen sulfide is a gas with a characteristic unpleasant odor and strong corrosive properties. Its presence in biogas can lead to corrosion of infrastructure and increase operational costs. To effectively remove H₂S, we recommend Sorbotech® GERS series activated carbons, which offer high efficiency and long service life.
Siloxane and VOC Elimination: Siloxanes, especially present in biogas from wastewater treatment plants and landfills, convert into silica during combustion, which deposits on engine and turbine components, leading to damage. Volatile organic compounds (VOCs) can further burden the purification process. To remove these contaminants, we recommend Sorbotech® GE series activated carbons.
To ensure maximum biogas purification efficiency, we recommend using Sorbofil® GPE carbon filters. These are high-performance filters designed for gas purification, with a construction that provides the longest possible contact time between the treated medium and the carbon bed. Made of HDPE material, these filters are corrosion-resistant, making them ideal for applications in environments with increased chemical aggressiveness. Sorbofil® GPE filters offer a wide range of gas flow, depending on the variant, from 350 to 5,500 m³/h.
