Bioalcohol production from lignocellulose – a comparison of processing schemes for different lignocellulosic raw materialsഀ Karin Øyaas*, Paper and Fibre Research Institute (PFI), Høgskoleringen 6B, NO-7491 Trondheim, Norway. ഀ This presentation will focus on conversion of different lignocellulosic raw materials to bioalcohols, ranging from bagass to hardwoods and softwoods. A comparison of different pretreatment processes (e.g. steam, strong acid, and sulphite based pretreatment) on the selected raw materials will be presented, focusing on saccharification potential of the pretreated raw materials, fermentability and lignin separation efficiency. The pretreatment processes studied show different efficiency, depending on the raw material input used. Process adjustments (e.g. pre-extraction of hemicelluloses to minimize formation of inhibitory compounds) were performed in order to improve the efficiency of different pretreatment processes for selected raw materials. The presentation will be based on work obtained in a 4-year Nordic collaboration in the field of bioethanol production, completed in December 2010, as well as findings in previous and ongoing national R&D projects headed by PFIഀ ഀ *: Further co-authors will be included later.ഀ
