Activated Carbon for Biogas Purification
Choose carbon around the target contaminants and the treatment stage in the biogas purification train.
Biogas Purification — Application Overview
Biogas can contain hydrogen sulfide, siloxanes and other contaminants at varying concentrations. Different targets and treatment stages can require standard, impregnated or catalytic carbon grades.
How Carbon Is Used
Carbon treatment combines adsorption or grade-specific reaction chemistry, depending on the contaminant and the media. Moisture, oxygen, temperature and gas composition can affect performance. Specify the conditions at the proposed filter location.
Selection Priorities
Contaminant priority
Identify each target gas and the required outlet concentration.
Media chemistry
Review standard, impregnated or catalytic grades for the defined duty.
Operating control
Agree gas monitoring, temperature control and replacement criteria with the equipment team.
Grade Parameters & Purchasing Brief
Provide the biogas composition, target contaminants, flow, humidity and temperature. Identify the pretreatment stages and the gas-quality requirements downstream.
| Gas composition | Target contaminants, inlet levels and relevant background gases. |
|---|---|
| Moisture and oxygen | Humidity, dew point and oxygen content at the filter inlet. |
| Flow and bed | Gas flow, pressure, vessel dimensions and allowable pressure drop. |
| Grade data | Treatment chemistry and duty-specific adsorption or reaction data. |
| Replacement plan | Breakthrough measurements, monitoring and spent-media handling. |
Industry Uses
Biogas from digesters and landfill sites can differ substantially. Size and assess the carbon stage using the actual gas analysis and expected variation.

Foire aux questions
Is standard carbon suitable for every biogas contaminant?
Suitability depends on the target compound and operating conditions. Compare the proposed media chemistry and duty-specific data before selecting a grade.
What should I include in a sample request?
For a biogas trial, include inlet contaminant ranges, moisture conditions, bed dimensions and the breakthrough criterion. Specify the sample quantity and delivery destination.
Plan Your Carbon Evaluation
Request supply against the gas duty and vessel charge. Include the expected changeout frequency, packing format and handling requirements.
