Kinetic modelling of coking coal fluidity development ...
· Phase changes of the porous coal structure are connected mainly with its chemical properties. Over the last decades, attempts were made to do it based on structural analysis of coal itself as well as its extraction, oxidation, hydrolysis or pyrolysis products [10, 15, 16].Nevertheless, up until now, a specific single chemical formula was not proposed.
