Brief Introduction of Activated Carbon
Activated carbon is made from charcoal, nutshells and high-class
coal. It appears to be black, tasteless, nontoxic absorbent,
with large specific area (600-2000m2/g) and three class of pore
size distribution (macropore: effective radius is over 1000oA;
transition: 100-200oA; micropore: under 20oA) after a serial
of physical and chemical processions including carbonization,
activation, acid cleaned and washed. It has properties of both
physical and chemical adsorption, selecting and adsorbing matters
of small and macro molecular in gas and liquid phase to do functions
of crocking, refining, deodorization, sterilization, decontamination
and purification. Activated carbon is an essential industry
product for food, pharmaceutical, chemical, water treatment,
environment-protection, chemical, national defense and agricultural
industry.
