Abstract
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 m2/g, the pore volume decreased from 1.088 to 0.269 cm3/g, and the fraction of micropores linearly increased from 0.64 to 0.92 as the Cdaf of the test samples increased from 70.4 to 95.6%. It was shown that an increase in coal rank was responsible for the transition from a micro–mesoporous material to a nanoporous AC.中文翻译:
