In this study, the use of a bituminous coal for the
production of activated carbons with chemical activation was
investigated. The effects of process variables such as
chemical reagents, activation temperature, impregnation
ratio and carbonization temperature were investigated to
optimize these parameters. The resultant activated carbons
were characterized in terms of iodine number, BET surface
area, and total and micropore volumes. Acidic surface groups
were established by Fourier Transmittance Infrared
Spectroscopy (FTIR) technique.
