Özet

The main goal of this work was to study alkaline pretreatment of hazelnut shells (HSs) by utilization of NaOH and Ca(OH)2 with or without glycerol. The highest lignin recovery was obtained for NaOH-glycerol-pretreated HSs. This research also determined the efficiency of enzymatic hydrolysis where xylanase and cellulase were added to the pretreated residue. The highest amount of lignin of 63.2% was achieved when NaOH was used with glycerol in the pretreatment process. These findings revealed that the NaOH-catalyzed glycerol pretreatment applied in this study has great capability to be used in industrial applications.
