Research Progress of Lignocellulose Pretreatment Methods

Lignocellulose is the most abundant renewable biomass in nature. The pretreatment of lignocellulose can effectively reduce the crystallinity of substrate,improve the utilization rate of lignocellulose,and increase its added value. In this paper the traditional and new pretreatment technologies were summarized,and the advantages and disadvantages of different pretreatment technology were compared. The future development of lignocellulosic pretreatmeat was prospected in order to provide reference for exploring new pretreatment and degradation technologies.
