  1. 1. Rörflen som strömedel i djupströbäddar för nötkreatur

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Linnéa Holmström; [2014]
    Nyckelord :rörflen; strömedel; djupströbädd; damm; uppsugningsförmåga; ströåtgång;

    Sammanfattning : På grund av de blöta höstarna de senaste åren har priset på halm stigit. Intresset har därmed ökat för att börja odla och använda energigräset rörflen som alternativt strömedel. Rörflen slås sent på hösten eller tidigt på våren för att sedan balas i slutet på april, eller i början på maj. LÄS MER

  3. 2. 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.

  4. 3. Thermal pre-treatment of cellulose rich biomass for biogas production

    L3-uppsats, SLU/Dept. of Microbiology

    Författare :Pauline Demetriades; [2008]
    Nyckelord :biogas production potential; degradation rate; degradation potential; thermal pre-treatment; steam explosion; autohydrolysis; cellulose; lignin; oat straw; meadow grass; aspen; spruce; wet grain residue; batch experiment;

    Sammanfattning : Anaerobic digestion is one possible method to produce bioenergy from cellulose rich materials but the process techniques still need refinements to facilitate the production process. In this work the biogas potential from six different plant materials was evaluated and what effect a thermal pre-treatment had on this potential. LÄS MER
