Le sfide del settore
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.
