What is ACTIVATED CARBON?
ACTIVATED CARBON is a carbonized adsorbent which has a lot of micropore formed by reaction of gas or chemicals at high temperature.
It is said that three different types of pore have each different role.
1.Micro pore : <2nm
2.Meso pore : 2~50nm
3.Macro pore : 50nm<
The specific surface area of conventional activated carbon is about 1000m2/g.
This size is equivalent to 5 tennis courts.
We have higher surface area activated carbon whose surface area has more than 2,000m2/g (MAXSORB(R)), compared to standard activated carbon.
How to manufacture ACTIVATED CARBON
ACTIVATED CARBON is manufactured by carbonizing raw materials such as wood chips, coconut shells, and coal at high temperature and then making pore in the carbon through activation process.
There are two main methods of manufacturing activated carbon: gas-activated and chemical-activated.
We have both type of activated carbon : gas-activated carbon using steam and chemical-activated carbon using alkali metal compounds (KOH).
The above activated carbon is then washed, particle-size adjusted, and heat-treated as necessary.
