一种加压微波预处理木质纤维素的方法
摘要：
一种加压微波预处理木质纤维素的方法，它涉及处理木质纤维素的方法。它解决了现有木质纤维素的预处理方法存在用水量大、成本高、能耗大和还原糖的转化率低的问题。方法：取已干燥至恒重的木质纤维素，粉碎成末，然后加蒸馏水，加压微波处理后即完成。本发明达到了在保证预处理效果的前提下，缩短了处理时间，降低用水量，降低了生产能耗和成本，同时不造成二次污染，易于实现工业应用的目的。本发明中加压微波预处理条件相对于其它预处理方法温和一些，反应的温度压强要求都不是很高(反应温度110～150℃，压力0.1～0.5MPa)，安全性高，能耗小；不需要添加任何化学试剂，且反应时间短(仅为2～15min)，节省了成本。
摘要（英）：

The invention provides a method for carrying out pressurization microwave pretreatment on lignocellulos, relates to a method for treating lignocellulose, and solves the problems of large water consumption, high cost and energy consumption as well as low conversion rate of reducing sugar of the existing methods for pretreating the lignocellulose. The method comprises the following steps of: obtaining and pulverizing lignocellulose which is dried to constant weight, adding distilled water and finally carrying out pressurization microwave treatment. The method achieves the purposes of shortening treatment time, reducing water consumption, cost and energy consumption during production, avoiding secondary pollution and being easily applicable to industry. The method achieves milder condition of pressurization microwave pretreatment in comparison with other pretreatment methods, low requirement on reaction temperature and pressure (reaction temperature: 110-150 DEG C, the pressure: 0.1-0.5 MPa), high safety, low energy consumption, no need of chemical reagent, short reaction time (only 2 to 15 min) and cost saving.
