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

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

    Abstract : 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. READ MORE

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

    Author : Staffan Haugwitz; Institutionen för reglerteknik; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Rikard Malmbeck; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reactor water; Seaborgium; BWR; mixer-settlers; Dubnium; Bohrium; transactinides; centrifuges; speciation; SISAK; solvent extraction; Iodine; Rutherfordium;

    Abstract : 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. READ MORE

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

    Author : Jonas Rydfjord; Mats Larhed; Adriaan Minnaard; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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.

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

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

    Abstract : 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.
