MATHEMATICAL MODELLING OF REACTIONS TAKING PLACE DURING THE PROCESS OF COAL ORGANIC MASS EXTRACTION BY SOLVENTS
The liquefaction of coals followed by the extraction of the black products with the help of some solvents is a very complex process. For this reason, the knowledge of this process’s mechanism was extremely difficult to decipher. Hiel’s studies led to the proposal of several possible reaction mechanisms. Paying particular attention to the study of the Jiu Valley coal’s liquefaction, there could be underlined a mathematical pattern of the reactions that took place during the process. This model complies with the ones proposed by the literature in this filed.
