木质纤维素预处理技术研究现状与展望
Research status and prospect of lignocellulose pretreatment technology
摘要
Abstract
Lignocellulose is the most abundant renewable resource in nature,which can be used to produce energy products such as fuel ethanol and biodiesel,and is also the main raw material for the preparation of chemicals and papermaking.Lignocellulose is mainly composed of cellulose,hemicellulose and lignin,and its complex chemical structure limits its efficient utilization.Therefore,it must be pretreated to remove insoluble substances such as lignin and hemicellulose,so as to make it easier to be hydrolyzed by enzymes into fermentable sugars,thus improving the degradation and conversion rate of lignocellulose.Pretreatment technology can change the internal structure and sur-face properties of lignocellulosic materials,creating good conditions for subsequent enzymatic hydrolysis and saccharifi-cation.The research status of different lignocellulose pretreatment technologies is reviewed from four aspects of phys-ics,chemistry,biology and combined treatment.The pretreatment effects,advantages and disadvantages are summa-rized,and the future research directions are prospected,aiming to provide references for the degradation and utilization of lignocellulose biomass.关键词
