木质纤维素生物质预处理技术研究现状

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。

Status in Pretreatment Technologies of Lignocellulosic Biomass

In order to develop economic and efficient pretreatment technologies,the research progress on 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.
