Factory-direct activated carbon from our production base in Shizuishan, Ningxia
Gas & Vapor Phase Abatement
Match pellet or granular carbon to the contaminant, humidity, airflow, bed depth and pressure-drop limit before selecting diameter and activity.
Recommended carbon
Pellet activated carbon for controlled pressure drop in VOC and odor beds; granular carbon where the equipment and vapor duty favor GAC
Extruded pellet
Columnar activated carbon for gas-phase beds, available in common 1.5-8 mm diameters with CTC, hardness and pressure-drop requirements reviewed by system.
Mainly anthracite or bituminous coal
1.5 – 8 mm pellets
Granular · GAC
Coal based GAC with configurable mesh, iodine value, CTC, hardness and washing options for industrial filtration and adsorption beds.
Anthracite, bituminous coal or a selected blend
8x30, 12x40 mesh
Granular · GAC
Hard coconut shell GAC for water, air and precious-metal recovery systems, supplied in common mesh ranges with batch-specific quality confirmation.
Selected coconut shell · steam activated
8x30, 12x40, 20x50 meshGrade matching
Review the target contaminants, carbon grade, sizing and test requirements together.
Reference grades are comparison directions, not a guarantee of interchangeability. Confirm the required specification and application testing before substitution.
Specification
The reference ranges most RFQs start from, before process conditions narrow them down.
| Primary sourcing direction | Pellet activated carbon for controlled pressure drop in VOC and odor beds; granular carbon where the equipment and vapor duty favor GAC |
|---|---|
| Common pellet diameter | 1.5-8 mm available directions; 4 mm is widely requested |
| CTC activity | Typical pellet range: 40-90%; common grades are often 50-75% |
| Hardness | Typical pellet range: 90-97%; >=95% is a common target |
| Moisture | Typically <=5% |
| Apparent density | Typical pellet reference range: 400-700 g/L |
| Alternative gas tests | Butane activity, butane working capacity or a VOC-specific adsorption or breakthrough test |
No single carbon removes every VOC or odor compound. Selection must reflect the actual vapor, humidity, airflow and breakthrough target; reactive gases require a separate industrial-gas review.
Air-purification equipment reference. Carbon form and bed design must be matched to the vapor profile, airflow and pressure-drop limit.
For ventilation, exhaust and vapor-control systems, carbon selection is driven by the VOC or odor profile, humidity, airflow and allowable pressure drop. Pellet or granular carbon is reviewed for physical adsorption duties; reactive gases require a separate industrial-gas assessment.
Compare vapor identity and concentration with CTC, butane or application-specific adsorption data.
Define the odor compounds, humidity, peak loading and target outlet condition before selecting the media.
Review the hydrocarbon range, loading cycle and working capacity rather than equilibrium activity alone.
Match pellet diameter, bed depth, face velocity and change-out method to the installed equipment.
System design
Confirm these reference conditions against the actual process and equipment.
Superficial Gas Velocity
0.15 – 0.50 m/s
Empty Bed Contact Time (Gas EBCT)
1.5 – 6.0 seconds depending on VOC molecular weight and inlet concentration
Typical Carbon Bed Depth
0.5 – 1.5 meters
Inlet Relative Humidity (RH)
< 65%–70% RH recommended for physical VOC adsorption to avoid capillary water condensation
Inlet Gas Temperature
< 40–50 °C preferred
Particulate & Aerosol Pre-Filtration
MERV 13 / F7+ pre-filter required upstream to block dust, grease, and paint mist
Published design practice for sourcing reference, not a guarantee for a specific system.

FAQ
Its cylindrical shape supports controlled airflow and pressure drop. Diameter, bed depth and hardness still need to match the equipment.
Water vapor can compete for adsorption sites and reduce usable capacity for some organic vapors. Provide the expected humidity range so the carbon and bed design can be reviewed under representative conditions.
Provide contaminant identity and concentration, humidity, temperature, airflow, bed depth, pressure-drop limit, desired service life and replacement method.
