    Abstract : To develop anaerobic digestion (AD), innovative solutions to increase methane yields in existing AD processes are needed. In particular, the adoption of low energy pre-treatments to enhance biomass biodegradability is needed to provide efficient digestion processes increasing profitability. READ MORE

  3. 7. Combined production of bioethanol and biogas from wheat straw

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Victor Gustafson; [2015]
    Keywords : lactic acid; chemical engineering; biogas; enzymes; enzymatic hydrolysis; energy recovery; ethanol red; bioethanol; wheat straw; steam pretreatment; inhibitors; kemiteknik; Technology and Engineering;

    Abstract : Currently the production cost of lignocellulosic ethanol is considered to be relatively high. Large fractions of the production cost come from the raw material and the energy consumed in the distillation. Therefore it is desirable to have a process that yields high concentration of ethanol and maximizes the utilization of the biomass. READ MORE

  4. 8. Integrated Energy Recovery Scenarios of Biomass Residues in the Non-interconnected Island of Crete : A Pre-Feasibility Study in Greece

    University essay from KTH/Industriell ekologi

    Author : Tryfon Papalexandrou; [2015]
    Keywords : Biomass residues; biomass waste; renewable energy; power generation technologies; sustainable development; off-grid; multi-criteria analysis.;

    Abstract : The cornerstone of our production system is based on the concept “take, make, waste”. Moreover, the manufacture of a product requires the input of energy and raw materials which produce waste and products. The latter ultimately end up becoming wastes. READ MORE

  5. 9. Fuel Coolant Interaction of Liquid Tin.

    University essay from KTH/Fysik

    Author : Albin Cassirer; Daniel Gullberg; [2014]
    Keywords : ;

    Abstract :   In the case of a severe accident in a nuclear power plant the reactor may heat up, melt and mix with fuel material to form a substance called corium. In today's nuclear power plants the primary strategy to cool the corium in the event of a severe accident is to flood the ex-vessel cavity with water. READ MORE

  6. 10. Saccharification of lignocellulose

    University essay from Malmö högskola/Fakulteten för hälsa och samhälle (HS)

    Author : Mohamed Warsame; [2012]
    Keywords : Wheat straw; Saccharification; Cellulose; Hemicellulose; Pretreatment; Lignocellulose;

    Abstract : Den ökande efterfrågan på energi och den förväntade nedgången i råoljeproduktion har lett till ett enormt sökande efter nya energikällor.Cellväggen i växter består till stor del av lignocellulosa som i sin tur innehåller cellulosa och hemicellulosa. Dessa polysackarider är av stor betydelse för sökandet efter förnyelsebar energi. READ MORE
