Factory-direct activated carbon from our production base in Shizuishan, Ningxia
Biogas, Flue Gas & Process Gas Scrubbing
Define the gas composition and operating envelope first, then select carbon form, diameter, activity and any required impregnation.
Recommended carbon
Pellet or granular carbon for physical adsorption; selected impregnated grades for contaminant-specific chemisorption
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 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 or granular carbon for physical adsorption; selected impregnated grades for contaminant-specific chemisorption |
|---|---|
| Common pellet diameter | 1.5-8 mm directions; pressure drop and bed design determine the final diameter |
| CTC activity | Typical pellet range: 40-90%; common grades are often 50-75% |
| Hardness | Typical pellet range: 90-97% |
| Moisture | Typically <=5% |
| Gas-specific testing | H2S breakthrough, sulfur capacity, acid-gas capacity or another contaminant-specific test |
| Impregnation | Selected KOH, NaOH, KI, sulfur or other treatment reviewed by contaminant and safety requirements |
Gas-treatment selection is safety-critical. Suitability and service life require an application review and should not be inferred from iodine or CTC values alone.
Industrial gas-treatment system reference. Media selection requires the full gas composition, breakthrough endpoint and operating safety review.
Industrial gas treatment begins with the full gas composition and safety envelope, especially for H2S, sulfur compounds and other reactive contaminants. The review determines whether physical adsorption is sufficient or a contaminant-specific impregnated grade and breakthrough test are required.
Confirm the target trace contaminant, upstream carryover, operating pressure and allowable outlet concentration.
Specify the concentration range, moisture, oxygen level and breakthrough endpoint for sulfur-capacity testing.
Review impregnant compatibility, competing gases, reaction products and operating safety before grade selection.
Define the outlet limit, monitoring point, change-out procedure and spent-carbon disposal route.
System design
Confirm these reference conditions against the actual process and equipment.
Superficial Gas Velocity
0.15 – 0.40 m/s in deep fixed-bed lead-lag adsorber vessels
Empty Bed Contact Time (EBCT)
3 – 10 seconds for H2S/siloxane fixed beds (matched to inlet ppmv loading)
Oxygen & Moisture Requirement (H₂S)
≥ 0.5%–2.0% O₂ and 40%–80% RH required for catalytic oxidation of H₂S to elemental sulfur
Bed Ignition & Thermal Safety
High ignition temperature
Vessel Configuration
Lead-lag
Packaging for Gas Plants
500 kg / 1,000 kg bottom-spout FIBC bulk bags for rapid pneumatic or gravity vessel loading
Published design practice for sourcing reference, not a guarantee for a specific system.
Grade review
Full gas composition, target contaminant and concentration, humidity, temperature, pressure, airflow, bed size, pressure-drop limit, required outlet concentration, quantity and destination.

Recommended qualification path
FAQ
Sometimes, but mixed streams can involve competitive adsorption, humidity effects and reaction safety. A full composition and operating range are required before grade selection.
Provide contaminant loading, airflow, temperature, humidity, bed dimensions, target outlet concentration and operating schedule. A pilot or application model may still be required.
Yes. SGS, Intertek, Bureau Veritas, TUV, CCIC or another agreed organization can be arranged under the contract, with scope and cost confirmed in advance.
