BG
*2**0 is a kind of briquetted activated carbon developed by SHANXI
XINHUI for water treatment,deodorization and separation of
components of flow system. The production processes are
accomplished by using one combination of the following steps:
1.) Carbonization: Material with carbon content is pyrolyzed at
temperatures in the range of **0–**0℃, in absence of oxygen
(usually in inert atmosphere with gases like argon or
nitrogen).
2.)Activation/ Oxidation: Raw material or carbonised material is
exposed to oxidizing atmospheres (carbon monoxide, oxygen, or
steam) at temperatures above **0℃, usually in the temperature
range of **0–***0 ℃. The product is also designed to comply with
all the applicable provision of ASTM standard for briquetted
activated carbon, the stringent extractable metals requirements of
NSF standard .
