Activated carbons can be produced from coals by a variety of thermal and chemical-thermal methods. A method related to the present paper is the chemical treatment of coal with aqueous KOH first at relatively low temperature (315-482{degrees} C), followed by carbonization at higher temperatures in the range of 704-982{degrees} C. In previous publications we have shown that temperatures as low as 75{degrees}C in the first step, followed by carbonization at 600-900{degrees}C gave good quality, high surface area, active carbons. Activated commercial carbons produced from coal are used for water purification, solvent recovery, supports for catalysts and for SOx and NOx removal from gas streams. This paper describes how varying certain parameters of coal-based catalysts could optimize their activity for dehalogenation of halogenated aromatic compounds.
