In this study activated carbons were prepared from three Australian bituminous coals. The influence of coal oxidation on the carbonization and activation processes and the structure of the resulting activated carbons were explored. The oxidation was conducted at 200°C in 0, for 6 hours. During the o
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
