Buy Biogas Activated Carbon

Activated carbon is a necessary step in biogas purification, primarily to remove problematic contaminants. It has the ability to adsorb hydrogen sulfide (H₂S), which is a corrosive, poisonous gas, and several different siloxanes that produce damaging deposits upon combustion, both of which are critical to remove during the purification process. The crucial function of activated carbon depends on its large surface area for physical adsorption. There are also forms of activated carbon that are chemically impregnated and these conditions allow H₂S to be catalytically converted to inert products.
 
Activated carbon is employed in filter beds that treat corrosive raw biogas as it flows through the activated carbon by-products and exits the carbon filtration. Activated carbon not only removes potentially harmful H₂S and siloxanes, protecting downstream equipment (like engines), and allowing the use of fuel or injected biogas into the electrical grid; it also assists in the overall purification of biogas, and presents an added level of operational safety in biogas purification.

업계 과제

Material Performance Limitations

  • Adsorption Selectivity: Activated carbon exhibits non-selective adsorption, capturing CO₂ and moisture alongside target contaminants like H₂S or siloxanes, reducing effective capacity for primary pollutants.
  • Pore Clogging: Particulates, oil mist, or tars in biogas physically block micropores ("pore poisoning"), diminishing surface area and adsorption efficiency over time.

Sensitivity to Operational Conditions

  • Humidity Interference: High moisture levels (>70% RH) compete with contaminants for adsorption sites, significantly lowering H₂S removal performance, especially in humid climates.
  • Temperature Instability: Elevated biogas temperatures (e.g., >40°C) reduce adsorption capacity and may trigger desorption of captured pollutants.

System Integration and Maintenance

  • Saturation Management: Finite adsorption capacity necessitates frequent carbon replacement or regeneration, risking pollutant "breakthrough" if not timely addressed.
  • Regeneration Complexity: Thermal/chemical regeneration is energy-intensive and may incompletely restore capacity or release trapped pollutants, requiring secondary treatment.
