Originally, organic solvents are used to extract lignin from lignocellulosic material in pulping process. Organosolv pretreatment is similar to organosolv pulping except the degree of delignification. This process uses either low or high boiling point solvents. Low boiling point solvents such as methanol and ethanol have been limited because they are highly volatile and flammable. As an alternative method, high boiling point solvents such as ethylene glycol and glycerol can be used. Although many studies have been carried out in the area of low boiling point organoslov pretreatment, very limited research has been performed in the high boiling point organoslov pretreatment. One of most obvious advantages for high boiling point pretreatment solvent was that the pretreatment can be conducted under atmospheric pressure, resulting in a significant decrease of the equipment cost. However, the relatively high cost of solvents significantly decreases this advantage. The main objective of this study was to investigate the effect of solvent type on the waste-paper pretreatment. Pretreatment was conducted over a range of conditions including sulfuric acid concentrations of 1~3%, temperature of 140~160, and reaction time of 10~30 minutes.
