Acidic hydrolysis of a birch (Betula pendula) xylan produced by a novel semi-industrial-scale aqueous-based and highly sustainable method was studied in a batch reactor. Five commercial acidic heterogeneous catalysts were screened and significant differences in their performance were observed. Dowex 50WX2-100 was selected for further studies and the influence of the reaction parameters, including stirring speed, pH (0.5–1.5), temperature (115–145 °C) and catalyst particle size (50–400 mesh) were studied. The goal was to maximize xylose yield by balancing between the kinetics of hydrolysis and the undesired degradation of monosaccharides.

使用商业催化剂从桦木 (Betula pendula) 中水解半工业水提取木聚糖：动力学和建模

在间歇反应器中研究了通过新型半工业规模水基和高度可持续方法生产的桦木 ( Betula pendula ) 木聚糖的酸性水解。筛选了五种商业酸性多相催化剂，观察到它们的性能存在显着差异。选择 Dowex 50WX2-100 进行进一步研究，并研究了反应参数的影响，包括搅拌速度、pH（0.5-1.5）、温度（115-145°C）和催化剂粒径（50-400 目）。目标是通过平衡水解动力学和不希望的单糖降解来最大化木糖产量。
