title: Modeling of the hydrolysis of sugar cane bagasse with hydrochloric acid.
abstract: Sugar cane bagasse was hydrolyzed under different concentrations of hydrochloric acid (2-6%), reaction times (0-300 min), and temperatures (100-128 degrees 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 degrees 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.
