Kinetics of co-pyrolysis of sawdust, coal and tar

Two coals, sawdust and coal tar were selected to prepare briquettes. Thermogravimetric analyses at three heating rates (i.e. 10, 20 and 30 °C/min) and up to 1000 °C were carried out with the briquette components. Four blends were prepared and the experimental decomposition profiles were compared wit...
