Abstract : This work examines the effect of both absolute pressure (range 1–6 bar) and peak temperature (range 350–800 °C) during pyrolysis of acacia wood in a macro-TG on the yield and CO2 gasification reactivity of the resulting charcoal. A central composite design was used for the experiments. The results of statistical analyses showed satisfactory agreement between the experimental results (charcoal yield and charcoal CO2 gasification reactivity) and model predictions. Both charcoal yield and reactivity decreased with an increase in temperature but increased with an increase in pressure. An increase in pyrolysis pressure increased charcoal yield and decreased reactivity. The temperature had a more significant effect on charcoal reactivity than pressure, and their interaction was not significant. The optimal conditions for the preparation of reductant charcoal were found to be a peak pyrolysis temperature of 617 °C and an absolute pressure of 6 bar. (Résumé d'auteur)
