Progress of Lignocellulose Pretreatment Technologies of Cellulosic Ethanol

Cellulose materials used to produce bioethanol is the most promising route for biofuel production.The research progress of pretreatment technologies was reviewed in this paper.Hot compressed water pretreatment without chemical additions and recovery was recommended to be the most promising for industrialization prospect.Inspired by hemicellulose biorefinery,the production of value-added products such as furfural and functional sugars during lignocellulose pretreatment in domestic enterprises decreases the cost of cellulosic ethanol production and realizes the comprehensive utilization of biomass.what's more,industrial scale plants have been built.
