What Is Pelletized Activated Carbon (EAC)?
Pelletized or extruded activated carbon (EAC) forms cylindrical particles for packed gas-treatment beds. A uniform pellet can help maintain predictable airflow, but diameter, strength and adsorption behavior still need to match the gas stream.
Purchasing Summary
| Buying brief | Provide gas flow, inlet concentration, temperature, humidity, vessel dimensions and allowable pressure drop. Ask for the proposed pellet diameter, strength, dust level and a relevant gas-phase test rather than relying on an unrelated iodine value. |
|---|---|
| Documents and packing | Identify the test report, destination-market requirements, packing and labeling needed for your order. |
| Order details | Confirm sample quantity, bulk quantity, destination and required delivery date. |
For a replacement bed, include the current pellet diameter and existing media specification.
Design the gas bed before choosing pellet diameter
For ventilation, VOC-control and solvent-recovery beds, cylindrical pellets are used in packed adsorbers. Pellet diameter affects packing and airflow, while feedstock or binder can change the finished grade. Confirm application restrictions and required gas-phase properties before comparison.
State the breakthrough criterion and whether the bed will be regenerated so candidate grades can be compared under a relevant test plan.
If the target requires treated media, start with the chemistry questions on our Carbone attivo impregnato page.
Grade Selection Checks
| Selection factor | What to review |
|---|---|
| Pellet diameter | Compare airflow and pressure drop in the actual bed |
| Adsorption evidence | Use a gas-phase test relevant to the target vapor |
| Binder and raw material | Confirm formulation restrictions and finished-grade strength |
How to Evaluate Pelletized Activated Carbon (EAC)
Run candidate grades under the same gas mixture, humidity, temperature and flow. Track outlet concentration and pressure drop against a defined breakthrough criterion.
Choose a Grade for Your Process
Plan regeneration or changeout before sizing full-volume supply; for mixed vapors, list target components and concentrations for the grade review.
Ask for a gas-phase test report that names the target vapor, test conditions and breakthrough endpoint.
Pelletized Activated Carbon (EAC) Applications
VOC exhaust and solvent-vapor adsorption
For VOC removal, select pellet dimensions around airflow, bed depth and pressure-drop limits. For solvent recovery, include the solvent mixture and regeneration conditions in the grade review.
Odor and process-gas treatment
Industrial odor or gas polishing may call for standard, catalytic or impregnated media. Temperature, moisture and target chemistry determine whether an untreated pellet is adequate.
Domande frequenti
What does EAC mean?
EAC denotes extruded activated carbon, typically formed as cylindrical pellets. Diameter and length distribution should be specified for the adsorption bed.
Why do gas beds often use carbon pellets?
Uniform pellets provide a predictable packing form and can help manage airflow and fines. Pressure drop still depends on size, bed depth and flow.
Which pellet diameter should I specify?
Use the vessel design, face velocity, contact time and allowable pressure drop. Confirm the proposed size against screens and filling procedures.
Can standard pellets remove every odor gas?
No. Some target gases may require a catalytic or impregnated grade. Identify the gas rather than selecting from a generic odor claim.
Can solvent-recovery pellets be reused?
Recovery and regeneration depend on solvent chemistry, equipment and media stability. Confirm the approved operating and safety procedure for the specific system.
What is required for an EAC inquiry?
Provide vapor composition, concentration, airflow, humidity, temperature, bed dimensions and pellet size. Include regeneration requirements, order quantity, packing and destination. Use our specification checklist to request the relevant TDS, COA and SDS.
