Abstract: Pretreatment is the key step for transformation of lignocellulosic biomass to fuel ethanol. The research status of several common pretreatment technologies were reviewed, the advantages and disadvantages of different pretreatment technologies were also analyzed comparatively. The futural development of lignocellulosic biomass pretreatment technologies was also prospected. The paper was expected to provide reference for the transformation technologies optimizing of lignocellulosic biomass.

Key words: lignocellulosic biomass, pretreatment technology, bioethanol
