Study of subbituminous coal chars: Effect of heat treatment temperature on their structural characteristics

Changes in the apparent surface area that are produced by carbonisation of a subbituminous coal at different temperatures are followed by adsorption of CO2 at 273 K and 298 K, the Dubinin—Radushkevich equation being used. Activated diffusion effects are found for the char samples prepared at 973 and...
