The acid-leached char produced in high yield by the pyrolysis of the potassium salt of a brown coal (Yallourn seam, Victoria, Australia) is shown to have an internal surface area in excess of 1100 m\*/g without the need for activation. Tabletting, or extrusion, of the potassium salt of the coal perm

Activated carbons prepared from two bituminous coals were used to adsorb phenol in aqueous solutions. The major diรพ erence between the coal precursors is the oxygen content. The carbon preparation consisted of carbonization of the coals followed by activation in to various CO 2 extents of burn-oรพ .
