Abstract: Ethanol and other biofuels produced from lignocellulosic biomass represent a renewable, more carbon-balanced alternative to both fossil fuels and corn-derived or sugarcane derived ethanol. Unfortunately, the presence of lignin in plant cell walls impedes the breakdown of cell wall polysaccharides to simple sugars and the subsequent conversion of these sugars to usable fuel. The pretreatment of lignocellulose could largely destroy the structure of cell walls and released the cellulose, then improved the accessibility between cellulase and cellulose, what’s more, the hemicellulose released could be used in many ways. This paper explicitly introduces different pretreatment technologies of lignocellulosic materials in recent years, and evaluated their advantages and disadvantages. Some valuable technologies with low power consumption, high efficiency and low pollution were recommended to guide the industrial application of ethanol production fromlignocellulose.
