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

    Författare :Alma Masic; [2013]
    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

  2. 2. Modeling, Control and Optimization of a Plate Reactor

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology, Lund University

    Författare :Staffan Haugwitz; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mid-ranging control; transition control; start-up; exothermic reaction; chemical reactor; modeling; process control; optimization; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : A new chemical reactor, the Alfa Laval Plate Reactor, is being developed by Alfa Laval, a Swedish world-leading heat exchanger company. The plate reactor combines the high-heat-transfer capabilities of plate heat exchangers with the efficient mixing and reaction control typical of microreactors. LÄS MER

  3. 3. Applications of On-Line Continuous Solvent Extraction in Nuclear Chemistry

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology, Lund University

    Författare :Rikard Malmbeck; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reactor water; Seaborgium; BWR; mixer-settlers; Dubnium; Bohrium; transactinides; centrifuges; speciation; SISAK; solvent extraction; Iodine; Rutherfordium;

    Sammanfattning : Methods and procedures for on-line continuous chemical separation of iodine species in reactor water and for transactinides in heavy element chemistry have been developed. Radioiodine is one of the more important fission products in terms of nuclear reactor safety due to its high fission yield, significant radiobiological hazard and potential volatility. LÄS MER

  4. 4. Palladium(II)-Catalyzed Addition Reactions Synthesis of Aryl Amidines and Aryl Ketones

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jonas Rydfjord; Mats Larhed; Adriaan Minnaard; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palladium; Catalysis; Palladium II catalysis; Synthesis; Addition Reactions; Cyanamide; Amidine; Aryl Amidine; Nitrile; Ketone; Aryl Ketone; Carbopalladation; Continuous-flow; Continuous flow; Microwave heating; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Palladium-catalyzed reactions have become one of the most important tools in modern organic chemistry due to its ability to catalyze the formation of new carbon-carbon bonds.The aim of the work presented in this thesis was to develop new palladium(II)-catalyzed addition reactions.

  5. 5. From torrefaction to gasification Pilot scale studies for upgrading of biomass

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Martin Strandberg; Anders Nordin; Linda Pommer; Jaap Kiel; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Torrefaction; biomass; pilot scale; continuous reactor; grindability; entrained flow gasification; degree of torrefaction; biomass powder;

    Sammanfattning : Increasing the share of biomass, preferably by replacing fossil fuels, is one way to mitigate the present climate change. Fossil coal can be directly replaced by co-combustion of coal and biomass and fossil engine fuels (gasoline and diesel) could potentially partly be replaced by synthetic renewable fuels produced via entrained flow gasification of biomass.
