Higroscopicity of Charcoal Produced in Different Temperatures

Abstract: This research aimed to evaluate hygroscopicity of charcoal produced under four different final carbonization temperatures. For evaluation of hygroscopicity charcoal samples were conditioned in environments with controlled temperature and relative humidity, using saturated salt solutions. The final carbonization temperature significantly influenced the products yields and the properties of charcoal. The charcoal produced in the final temperature of 750 °C showed the highest adsorption capacity of water, indicat… Show more

“…Ela decresce até temperaturas próximas a 550 °C, aumentando consideravelmente a partir desse patamar. Diante do aumento da densidade, o volume poroso diminui, e com ele a capacidade de adsorção relacionada à porosidade (DIAS JÚNIOR et al, 2016). Tabela 4.…”

“…Os modelos ajustados (Figura 2) mostram ótimos coeficientes de determinação significativos para a probabilidade adotada. Essas observações relacionam à porosidade do carvão vegetal, característica associada a adsorção e resultantes das propriedades da madeira e das temperaturas de carbonização aplicadas (BROWN et al, 2006;YU et al, 2006;BERGERON et al, 2013;DIAS JÚNIOR et al, 2016). …”

“…This is true because the fixed carbon content of the charcoal increases as the temperature increases during the carbonization process (Trugilho and Silva, 2001;Dias et al, 2016). The result would be, for example, charcoal with lower tar yields as compared to charcoal produced at a lower final carbonization temperature.…”
