<br/><br/> <br/><br/>ABSTRACT<br/><br/>The objectives of the present work were to determine the properties of wood and charcoal from<br/>Eucalyptus clones and assess impacts of charcoal features on the CO2 gasification reactivity<br/>and to compare with coke reactivity. Gasification reactivity was performed using charcoal<br/>particles in a furnace setup at 820 °C, under CO2 atmosphere. The results show that there is<br/>wood variability among evaluated clones and strong correlations between wood and charcoal<br/>properties. All charcoals had higher reactivity in comparison to coke. The decrease in porosity<br/>and increase in apparent density in Eucalyptus wood led to a slight decrease of CO2 gasification<br/>reactivity. In addition, strong positive correlation between charcoal reactivity and potassium<br/>concentration (K) was found.<br/><br/>Keywords: CO2 gasification, reductant materials, biocarbon.
