   Sammanfattning : The change in climate as a consequence of anthropogenic activities is a subject ofmajor concerns. In order to reduce the amount of greenhouse gas emissions inthe atmosphere, the utilization of renewable, fossil-free power generationapplications becomes inevitable. LÄS MER

3. 12. Integrated production of bioethanol and biogas from agricultural residue : comparison of pretreatment methods using mass flow and energy yields analysis

   Master-uppsats, SLU/Dept. of Molecular Biology (until 131231)

   Författare :Debebe Yilma Dererie; [2010]
   Nyckelord :lignocellulose; biofuel; bioenergy; biorefinery; biogas; ethanol; pretreatment; enzymatic saccharification; fermentation;

   Sammanfattning : Lignocellulosic biomasses are believed to reduce the conflict for resource between food and energy production that was criticized in the first generation biofuel production. The aims of this study were two; the first being to compare the effects of three lignocellulose pretreatment methods, lime pretreatment and two steam pretreatment methods, either with or without prior acid impregnation, on the production of bioethanol and biogas from oat straw.
