摘要:为了研究经济高效的预处理技术,综述了近 10 年国内外在木质纤维素预处理技术方面的研究,
对物理法、物理-化学法、化学法、生物法等预处理技术进行了重点分析,发现稀酸处理法、蒸汽爆破法和
生物法等技术极具潜力,但目前的研究仍存在不足,今后还需研究成本低、产率高、污染小的预处理技
术。最后对预处理技术的发展提出了建议。

Abstract:
pretreatment of lignocellulose at home and abroad in recent 10 years was reviewed detailedly. And the
pretreatment processes, such as physical methods, physical-chemistry methods, chemical methods and biologic
methods were emphatically analyzed, from which dilute acid pretreatment method, steam explosion
pretreatment method and biological pretreatment method were found to be most development potential.
Pretreatment methods with low cost, high yield and less pollution are needed to be developed for shortages of
the existing methods. And some proposals for development of pretreatment technologies were put forward as
well.
