Abstract

Fuel grade bioethanol can be produced from a number of lignocellulosic biomass sources. In the present paper the enzymatic hydrolysis of giant reed (Arundo donax) at high biomass loadings up to 20% (w/v) was investigated. Two pretreatment technologies were used: one step steam explosion (SE) with and without acid catalyst and the novel pilot process from Chemtex consisting in a two steps pretreatment. The results of the biomass composition after different pretreatment conditions along with the corresponding enzymatic hydrolizability at low solids loading, indicated that the best pretreatments were the acid catalyzed steam explosion (ACSE) at 200°C and the Chemtex process in which the SE step was carried out at 206 for 4min. Various process configurations, including biomass and enzymes fed-batch, were investigated to avoid excessive viscosities and increase the cellulose conversion. Novel enzymatic preparations from Novozymes, Cellic™ Ctec1 and Cellic™ Ctec2, were used for the biomass saccharification.
