  1. 16. 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

  3. 17. Impact of pre-treatment on the stability and leachability of three different wastes

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Hanna Modin; [2007]
    Nyckelord :waste management pre-treatment; municipal solid waste; leachate fractionation; heavy metals; Miljöstudier; waste management stabilisation; humic acid; Environmental studies; Earth and Environmental Sciences;

    Sammanfattning : The effect from mechanical-biological pre-treatment (MBT) of wastes in Sweden and Germany has been studied. The organic matter and biological activities were studied and compared. Other parameters such as heavy metals and nutrients were examined and related to the organic matter. LÄS MER
