Effect of Temperature and Time on the Steam Pretreatment of Hazelnut Shells for the Enzymatic Saccharification

Saturated steam pretreatment of hazelnut shells was studied for fermentable sugars after enzymatichydrolysis. The elevation of temperature (from 160 to 200 °C) and time (0–30 min) of steam pretreatment were investigated. Hemicellulose removal (%) gradually increased with increasing pretreatment temp...

Description
Summary:Saturated steam pretreatment of hazelnut shells was studied for fermentable sugars after enzymatichydrolysis. The elevation of temperature (from 160 to 200 °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 t e biomass was treated at 200 °C for 30 min. Maximum cellulose digestibility (46%) was obtained at the conditions of 180 °C for 30 min (46%). Glucose recovery ranged from 337 to 456 mg/ g initial solid.
