The hydrolysis process of a real fraction of arabinoxylans derived from wheat bran was studied. The influence of catalyst type and loading, reaction time and different metal cations were discussed in terms of the hydrolysis yield of arabinose and xylose oligomers as well as the formation of furfural as degradation product. A high yield of arabinoxylans into the corresponding monomeric sugars (96 and 94% from arabino- and xylo-oligosaccharides, respectively) was obtained at relatively high temperatures (180°C) and short reaction times (15min) with a catalyst loading of 4.8g of RuCl/Al-MCM-48 per g of initial carbon in hemicelluloses.
研究了从麦麸中提取的阿拉伯木聚糖真实分数的水解过程。讨论了催化剂类型和负载量、反应时间以及不同金属阳离子对阿魏糖和木糖低聚物水解产率以及糠醛作为降解产物形成的影响。在相对较高的温度（180°C）和较短的反应时间（15 分钟）下，用 4.8g RuCl/Al-MCM-48 催化剂负载量（每克初始碳中半纤维素），可获得较高的阿拉伯木聚糖转化为相应单糖的产率（阿魏糖和木糖低聚糖分别为 96%和 94%）。
