  1. 11. Optimal steady-state design of bioreactors in series with Monod growth kinetics

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Molin Hanna; [2018]
    Nyckelord :bioreactor; CSTR; PFR; optimization; modelling; Monod kinetics; decay rate; bioreaktorer; CSTR; PFR; optimering; modellering; Monod-kinetik; avdödningshastighet;

    Sammanfattning : Bioreactors are used to carry out bioprocesses and are commonly used in e.g. biogas production and wastewater treatment. Two common hydraulic models of bioreactors are the continuous stirred tank reactor (CSTR) and the plug-flow reactor (PFR). LÄS MER

  3. 12. Hydrodynamic cavitation applied to food waste anaerobic digestion

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :David Tran; [2016]
    Nyckelord :Anaerobic Digestion; Biogas; Pre-treatment; Hydrodynamic cavitation;

    Sammanfattning : Innovative pre-treatment methods applied to anaerobic digestion (AD) have developed to enhance the methane yields of food waste. This study investigates hydrodynamic cavitation, which induce disintegration of biomass through microbubble formations, impact on food waste solubilisation and methane production during following AD.

  4. 13. The effects of trace elements on the microbial communities of thermophilic biogas production

    Master-uppsats, SLU/Dept. of Microbiology

    Författare :Robin Hagblom; [2016]
    Nyckelord :biogas; thermophilic; trace elements; ammonia; SAO; fhs;

    Sammanfattning : The increasing need for alternatives to fossil fuels and traditional waste management systems can be simultaneously addressed by the production of biogas using organic waste as input material. The biogas produced can be used directly for energy production or upgraded to increase methane purity for use in the engines of motor vehicles. LÄS MER

  5. 14. Anaerobic Digestion of Fractionated and Non-fractionated Sugar Beet Tops

    Master-uppsats, Lunds universitet/Bioteknik; Lunds universitet/Kemiska institutionen

    Författare :Johan Lindgren; [2014]
    Nyckelord :Anaerobic Digestion; Biogas; Biotechnology; Bioteknik; Technology and Engineering;

    Sammanfattning : Continuous stirred tank reactors (CSTR) and batch reactors were used to examine the difference in methane yields and process stability between fractionated and non-fractionated sugar beet leaves. The hypothesis of this project was that by reducing the amount of juice in the sugar beet leaves the amount of soluble sugars and other easily fermented compounds in the substrate will also decrease, and thereby lead to higher process stability.

  7. 15. Ammonia Dosing Control Strategy for heavy duty automotive SCR

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Rakshith Ramachandra; [2014]
    Nyckelord :;

    Sammanfattning : Selective Catalytic Reduction (SCR) has proven to be the frontrunner for the removal of nitrogen oxides (NOX) from exhaust gas. EURO VI emission regulations present a challenge from the control point of view, so as to achieve high NOX conversion while keeping the ammonia slip under control. LÄS MER
