    Sammanfattning : Gas turbines have served as economically profitable and reliable generators of power for the past few decades, and have mainly been used in simple and combined cycles. The increased restrictions on hazardous emissions and the increased demand for profitability have created new prospects for innovative power cycles. LÄS MER

  4. 3. Biogas Production from Citrus Wastes and Chicken Feather : Pretreatment and Co-digestion

    Författare :Gergely Forgács; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anaerobic digestion; pretreatments; co-digestion; economic analyses; citrus wastes; feather; Energi; material; Resursåtervinning; Resource Recovery;

    Sammanfattning : Anaerobic digestion is a sustainable and economically feasible waste management technology, which lowers the emission of greenhouse gases (GHGs), decreases the soil and water pollution, and reduces the dependence on fossil fuels. The present thesis investigates the anaerobic digestion of waste from food-processing industries, including citrus wastes (CWs) from juice processing and chicken feather from poultry slaughterhouses.

  5. 4. Bonding and Desorption Mechanismsof CO on Metal Surfaces

    Författare :Jörgen Gladh; Henrik Öström; Mats Götelid; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bonding; Desorption; CO; Metal; kemisk fysik; Chemical Physics; fysik; Physics;

    Sammanfattning : I have investigated two different systems CO/Fe(100) and CO/Ru(0001), toobtain new information on the binding and desorption processes. The twodifferent systems have served as a model system, one for a static examination,CO on iron, and for the dynamic case, CO on ruthenium. LÄS MER
