Coal columnar activated carbon for air purification, deodorization, a coal columnar activated carbon and gaseous impurity removal. The process is mainly through the following two steps.
1: in the absence of oxygen carbonization temperature range of 600-900 ℃ (usually under theuse of nitrogen or argon and other inert gases, carbon is the pyrolytic).
2 activation: in the condition of high temperature, temperature range of 600-1200 ℃, the rawmaterial or been carbonized material is placed to the oxidizing gas (carbon monoxide, oxygenwater vapor) activation.
This product conforms to a standard about columnar activated carbon American Standard in ASTM standard.
The scope of application
Mainly used for removal of pollutants in the air, and the gas separation and purification. |
