Coal based activated carbon originate from coal that
has undergone steam activation process to create its activated carbon
form. During activation, it creates millions of pores at the
surface of the carbon thus increasing the total surface area.
Activated carbon pores can be divided into three general sizes
Micro-pores (diameter in the range of less than 2 nm), Meso-pores
(diameter in the range of 2 – 25 nm), and Macro-pores (diameter in the
range of above 25 nm). Coal based carbon has mainly meso-pores
and macro-pores and due to its unique distribution of pores
diameter, coal based activated carbon are very popular in the gas phase
purification, potable water purification industries, wastewater
purification industries and aquarium/pond water purification industries.
