Technical data sheet & illustrative COA reference · Cylindrical or columnar pellets
Pellet Activated Carbon
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.
- Uniform cylindrical extruded pellets (1.5 mm, 2 mm, 3 mm, 4 mm, 6 mm, and 8 mm diameters) engineered for low pressure drop and high mechanical crush strength (>=95% hardness) in deep-bed gas scrubbers.
- Configurable gas-phase activity from 50% to 75%+ CTC (ASTM D3467) / 20–30%+ Butane Activity (ASTM D5742) for VOC abatement, solvent recovery, biogas desulfurization, and odor control.
- Available in standard virgin coal/coconut pellets as well as KOH, NaOH, KI, and sulfur-impregnated grades for H2S, acid gases, and mercury removal.
1Technical specifications
| Raw material | Primarily anthracite or bituminous coal powder; selected specialty grades may use wood or coconut carbon |
|---|---|
| Physical form | Cylindrical or columnar pellets |
| Standard sizing | Common diameters: 1.5, 2, 3, 4, 5, 6 or 8 mm; 4 mm is widely requested |
| Iodine value | Typical configurable range: 700-1,100 mg/g |
| CTC activity | Typical range: 40-90%; common grades are often 50-75% |
| Hardness | Typical range: 90-97%; >=95% is a common sourcing target |
| Ash | Typically <=12%; lower-ash gas grades require confirmation |
| Moisture | Typically <=5% |
| pH | Typically 8-11; impregnated grades depend on the impregnant |
| Apparent density | Typical range: 400-700 g/L |
| Custom manufacturing | Diameter, length, CTC, iodine value, hardness, loading density and selected KOH, NaOH, KI, sulfur or application-specific impregnation. |
Common methods include ASTM D3467 for CTC, ASTM D5742/D5228 for butane activity or working capacity, ASTM D3802 for hardness and ASTM D2854 for apparent density. Final guaranteed values and test methods must be agreed in the order specification.
