Abstract:
Arundo donax is a non edible biomass that can be used for energetic purposes thanks to the low inputs required for its growth. Biomass pretreatment was investigated by using the ENEA’s steam explosion (SE) batch plant. The temperatures were ranged from 196 up 210 °C and the treatment time was 5 minutes. At these conditions the products obtained appeared poor pupled as confirmed by the characterization of the water soluble fractions. Further optimizations were done by impregnating the biomass with small amounts of acids prior to the pretreatment. The acid catalyzed SE pretreatment produced products much more pulped that can be easily fractionated. On the whole, higher amounts of hemicellulose sugars were separated in the liquid fractions already as monomers. In the present paper, the effectiveness of the SE pretreatments with and without acid was discussed in terms of the relevant enzymatic hydrolizability. The results of the conventional SE conditions were then compared with those obtained by testing materials pretreated by the Chemtex technology as part of the European project BIOLYFE.
