The production of activated carbon from a bituminous coal

2020-7-16 · Particularly, bituminous coals are the main precursor for the production of activated carbon (Walker, 1986). This study is to demonstrate that an acceptable activated carbon adsorbent can be produced from an Illinois-basin bituminous coal. The adsorbent-behaviour of that Illinois coal-carbon is then compared with the performance of a commer-
