Thermochemical conversion of coal from rio turbio minefield with a sustainable energy plantation: On kinetics of co-pyrolysis

Kinetics of co-pyrolysis of blends composed of equal proportions of the subbituminous coal from the Río Turbio minefield and stems from giant reed (Arundo donax L.), as representative biomass from sustainable energy plantations, is characterized accounting for the individual pyrolytic behavior and m...
