Technical Data Sheet
Coal Powdered Activated Carbon
Fine, fast-acting, and built for the refining line.
The CK-PAC-CB series is a powdered activated carbon produced by steam activation under stringent operating conditions. Ground to pass 200 mesh, it works far faster than a granular carbon because every particle is already at the surface.
It is optimised for edible oil refining — decolourising and the removal of dirt and micro-impurities. Its large pore volume and rapid adsorption also make it well suited to non-edible oil refining and waste water purification.
Two grades are available, separated by iodine value. Choose the one that matches the colour load you need to strip.
CK-PAC-CB — Coal Based Powder

Where two figures are given they are listed in grade order: CK-PAC-CB-I500-600, then CK-PAC-CB-I700-800.
Technical Data Sheet
Wood Powdered Activated Carbon
The highest iodine values we make, and the lightest.
The CK-PAC-WB series is a wood based powdered activated carbon produced by steam activation under stringent operating conditions. Wood gives a more open pore structure and a much lower bulk density than coal, so it lifts large colour bodies that a denser carbon leaves behind.
It is optimised for water treatment and edible oil refining — decolourising and the removal of dirt, BOD, COD and micro-impurities, and is widely used in non-edible oil refining and food applications.
Four grades are available, from 800 to 1100 mg/gm iodine value. The full specification for all four is set out below.
CK-PAC-WB — Wood Based Powder
| Methylene Blue Value (Min) | 150 / 200 / 250 / 300 mg/gm | — |
|---|---|---|
| Iodine Value | 800 / 900 / 1000 / 1100 mg/gm | ASTM D4607 |
| Moisture (%) | Below 5 / Below 3 / Below 3 / Below 3 | ASTM D2867 |
| Bulk Density | 470 / 360 / 340 / 340 Kg/m³ | ASTM D1895 |
| Ash | < 12% / < 9% / < 9% / < 9% | ASTM D2866 |
| pH | 9 – 11 | ASTM D3838 |
| Mesh Size | 90% passing through 200 mesh | ASTM D2862 |
Values written as four figures are listed in grade order: CK-PAC-WB-I800, CK-PAC-WB-I900, CK-PAC-WB-I1000 and CK-PAC-WB-I1100.
