Raw materials of the activated carbon:
- Wood: coconut shell, nut shell, peach shell, apricot shell, jujube shell, sawdust and charcoal.
- Coal: high quality of the anthracite coal from Shanxi province.
Shape and size of the activated carbon:
1. Granular: 4-8, 5-10, 6-12, 8-16, 8-30, 10-24, 12-20, 20-40, 40-60, 60-80mesh
2. Powder: 80, 100, 150, 200, 325mesh
3. Columnar: 0.9, 1.5, 2.0, 3.0, 4.0, 5.0, 6.0, 8.0, 9.0mm,
4. Spherical: 1-2, 2-4, 4-6, 6-8mm
Manufacturing process:
- Chemical method
- Physical method
It adopt the anthracite as the raw materials. The produce process is crushing, drying, carbonization, activation, packing.
Commonly size: 0.9, 1.5, 2.0, 3.0, 4.0, 5.0, 6.0, 8.0, 9.0mm
Features of the columnar activated carbon:
- High mechanical strength.
- Internal void developed.
- Good adsorbability.
- Easy regeneration and cheap price.
Usage of the columnar activated carbon:
- Life waste water purification, industry water treatment, drinking water purification.
- Gas phase adsorption, oil water separation. It widely used to processing plant, gas station, organic solvent recovery.
- Wipe off harmful gas. Such as the gas-mask, vehicle exhaust and so on.
