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.
甘蔗渣在不同浓度的盐酸（2%-6%）、反应时间（0-300分钟）和温度（100-128摄氏度）条件下进行水解。对所得糖类（木糖、葡萄糖、阿拉伯糖和葡萄糖）以及降解产物（糠醛和乙酸）进行了测定。基于塞曼模型和双组分模型，建立了用于预测水解产物中这些化合物的动力学参数。利用阿伦尼乌斯方程研究了温度的影响。选择的最佳条件为128摄氏度、2%的盐酸以及51.1分钟。在这些条件下，得到了22.6克/升木糖、3.31克/升阿拉伯糖、3.77克/升葡萄糖、3.59克/升乙酸和1.54克/升糠醛。
