Formation of the Porous Structure of Fossil Coals upon Alkaline Activation with Thermal Shock
The porous structure of activated carbons (ACs) formed by fossil coals of different ranks upon alkaline activation with thermal shock (KOH, 800°C) was studied. It was established that the specific surface area of ACs decreased from 2012 to 818 m 2 /g, the pore volume decreased from 1.088 to 0.269 cm...
