Abstract:
The region of Navarra in Spain has important agriculture and agro-industrial outputs that can be used as feedstocks in a biorefinery. For this reason, several research organizations (1) have joined efforts to carry out a project for the definition of a biorefinery concept for the Navarra region. The project is divided in three work-packages: WP1-Feedstocks, WP2-Conversion processes and WP3-Biorefinery concept design. Within WP2, an evaluation of several conversion processes is being carried out. In this context, pretreatment assays using cereal straw as feedstock under diverse conditions (temperature, residence time and acid) have given a broad amount of slurries with high variability regarding its carbohydrate composition and their prone for enzymatic digestibility. These results have been used to correlate two important parameters when designing a biorefinery process, xylose concentration after pretreatment and glucan to glucose conversion yield after enzymatic hydrolysis. Both correlation formulas showed relative high values of R2 (> 0.87) assuring the precision of the predictions and becoming a useful tool for a biorefinery plant design.
