Typical sourcing range
Specifications buyers can use to prepare an RFQ
These are common or configurable manufacturing ranges, not a batch guarantee. Final acceptance values, methods and tolerances are confirmed in the signed product specification and batch COA.
| Raw material | Anthracite, bituminous coal or a selected coal blend |
|---|---|
| Form | Irregular granular activated carbon |
| Particle size | 4x8, 6x12, 8x16, 8x30, 12x20, 12x30, 20x40 or 30x60 mesh |
| Iodine value | Typical configurable range: 800-1,050 mg/g |
| CTC activity | Typical configurable range: 50-75% |
| Methylene blue | Typical optional range: 100-200 mg/g |
| Hardness | Typically >=90%; higher-hardness grades can be reviewed |
| Ash | Typical range: 8-15%; acid-washed grades can be lower |
| Moisture | Typically <=5% |
| pH | Typically 8-11; washed or acid-washed pH is configurable |
| Apparent density | Typical range: 450-550 g/L |
Send these fields for grade matching
Water or gas conditions, target contaminant, vessel design, mesh, target iodine or CTC value, quantity, packing and destination.
Application fit
Common use directions
- Municipal and industrial water treatment
- Wastewater polishing
- Air and VOC treatment
- Solvent recovery and filter vessels
Custom manufacturing
Fields that can be reviewed
Coal blend, mesh, iodine value, CTC, methylene blue, hardness, ash, acid washing, water washing and pore-structure direction.
Test-method note: Common methods include ASTM D4607 for iodine value, ASTM D3467 for CTC, ASTM D3802 for hardness and ASTM D2862 for particle-size distribution.
Grade selection
How to specify Coal Based GAC for a bulk order
Use the application, equipment and agreed test methods to turn a typical product range into a contract specification.
Selection factors
- Start with contaminant size, liquid or gas conditions and bed design before choosing an iodine or CTC target.
- Select mesh against vessel screens, flow rate, pressure drop and any backwash or regeneration procedure.
- Use washing, pH and ash limits when mineral carryover or downstream purity is important.
- For VOC service, add CTC, butane activity or a contaminant-specific test instead of relying on iodine value alone.
Quality checks to discuss
- ASTM D2862 particle-size distribution
- ASTM D3802 hardness
- ASTM D4607 iodine value
- ASTM D3467 CTC activity
- Batch COA and agreed sampling method
Contract boundary: The signed specification identifies guaranteed values, methods, sampling and tolerances. Website ranges remain sourcing references.

Document scope and timing are confirmed with the quotation, specification and shipment stage.
FAQ
Coal Based GAC purchasing questions
Selection starts with the liquid or gas conditions, contaminant class, bed design, mesh and required adsorption index. Iodine value alone does not define application performance.
Acid washing, water washing, controlled pH and lower-ash specifications can be reviewed. Customized MOQ and lead time depend on the requested values.
TDS and SDS can be supplied during quotation, and a batch COA can be supplied for each production or shipment batch.
