Abstract:Sugar cane bagasse was hydrolyzed under different concentrations of hydrochloric acid (2-6%), reaction times (0-300 min), and temperatures (100- 128°C). Sugars obtained (xylose, glucose, arabinose, and glucose) and degradation products (furfural and acetic acid) were determined. Based on the Saeman model and the two-fraction model, kinetic parameters for predicting these compounds in the hydrolysates were developed. The influence of temperature was studied using the Arrhenius equation. The optimal conditions selected were 128°C, 2% HCl, and 51.1 min. Using these conditions, 22.6 g xylose/L, 3.31 g arabinose/L, 3.77 g glucose/L, 3.59 g acetic acid/L, and 1.54 g furfural/L were obtained.
