Abstract

Saturated steam pretreatment of hazelnut shells was studied for fermentable sugars after enzymatic hydrolysis. The elevation of temperature (from 160 to 200 degrees C) and time (0-30 min) of steam pretreatment were investigated. Hemicellulose removal (%) gradually increased with increasing pretreatment temperature and time. 83 % of initial hemicellulose was removed when the biomass was treated at 200 degrees C for 30 min. Maximum cellulose digestibility (46%) was obtained at the conditions of 180 degrees C for 30 min (46 %). Glucose recovery ranged from 337 to 456 mg/g initial solid.
