  1. 1. Investigation of a Biofilm Reactor Model with Suspended Biomass

    Författare :Alma Masic; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wall attachment; suspended growth; substrate removal; reactor; biofilm; CSTR; mathematical model; MBBR; nitrification; optimization;

    Sammanfattning : Biofilms are compact, sessile microbial communities that attach to surfaces in aqueous environments. In wastewater treatment, they are especially important for removal of phosphorus and nitrogen, which, if released into a receiving water body, can cause severe eutrophication. LÄS MER

  3. 2. Model Reduction for Control of Stirred Tank Reactor Processes

    Författare :Veronica Olesen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QFT; CSTR; sensitivity functions; Model simplification; closed loop;

    Sammanfattning : Models of chemical processes have a tendency of being far too complex for controller design. In many cases these models are also too complex for simulation together with other sub-systems, due to long simulation times and numerical problems. LÄS MER

  4. 3. Caldicellulosiruptor Saccharolyticus: an Ideal Hydrogen Producer?

    Författare :Sudhanshu Pawar; Avdelningen för kemiteknik; []
    Nyckelord :Caldicellulosiruptor owensensis; Caldicellulosiruptor saccharolyticus; hydrogen; volumetric hydrogen productivity; biofilm; osmotolerance; wheat straw hydrolysate; evolutionary engineering; CSTR; UA reactor and uracil auxotrophy;

    Sammanfattning : Caldicellulosiruptor saccharolyticus is an extremely thermophilic, strictly anaerobic, Gram-positive and cellulolytic microorganism with a natural ability to produce hydrogen (H2) at nearly theoretical maximum yield, i.e. 4 mol/ mol of glucose. LÄS MER

  5. 4. Biogas production from lignocellulosic agricultural residues : microbial approaches for enhanced efficiency

    Författare :Tong Liu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Methane, produced through microbial anaerobic digestion of various organic materials, is seen as a promising sustainable bioenergy source with the potential to reduce the current dependence on fossil fuels. Among organic materials, lignocellulosic materials, especially agriculture residues, are highly interesting due to high abundance and potential for methane production. LÄS MER

  7. 5. Two-Stage Conversion of Land and Marine Biomass for Biogas and Biohydrogen Production

    Författare :Valentine Nkemka; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steam pretreatment; dry digestion; biogas; biohydrogen; Caldicellulosiruptor saccharolyticus; cadmium; anaerobic digestion;

    Sammanfattning : The replacement of fossil fuels by renewable fuels such as biogas and biohydrogen will require efficient and economically competitive process technologies together with new kinds of biomass. A two-stage system for biogas production has several advantages over the widely used one-stage continuous stirred tank reactor (CSTR). LÄS MER
