Abstract

Olive tree biomass (OTB) is an agricultural residue which can be used as raw material for bioethanol production. OTB was pretreated with 0.05-0.275 M FeCl(3) solutions at 120-180 °C for 0-30 min. Enzymatic hydrolysis yields were used for assessing pretreatment performance. Optimum FeCl(3) pretreatment conditions were found to be 152.6 °C, 0.26 M FeCl(3) for 30 min. Under such conditions, 100% of hemicellulose was removed, and enzymatic hydrolysis of pretreated solids resulted in a yield of 36.6g glucose/100g of glucose in the raw material. Hemicellulosic sugar recovery in the prehydrolysate was 63.2%. Results compare well with those obtained by other pretreatment strategies on the same raw material, confirming FeCl(3) solutions as a new, feasible approach for bioethanol production.
