Abstract

The suitability of oak shell wastes used as feedstock for bioethanol production was studied. The impacts of varying pretreatment parameters such as temperature,time,and alkali concentration of alkali pretreatment on enzymatic hydrolysis of oak shell were investigated. Results showed that pretreatment with 2% Na OH at 121 ℃( 0. 15MPa) for 60 min was optimal,which resulted in the highest delignification of 39. 34% and sugar yield of 606. 36 mg / g origin material. The ethanol concentration reached 11. 96 g / L after fermentation with Pachysolen tannophilus for 60 h,which was 85. 4 % of the theoretical yield.

Key words： oak shell; bioethanol; alkali pretreatment; enzyme saccharification; lignocellulosic biomass
