ABSTRACT

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