  1. 1. Selective oxidation over mixed oxide catalysts

    Author : Robert Häggblad; Lunds universitet.; Lund University.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; propane; catalysis; Selective oxidation; transition metal oxides; vanadium; molybdenum; methanol oxidation; ammoxidation; propene; acrylonitrile; formaldehyde;

    Abstract : Popular Abstract in Swedish En spännande utmaning för forskare inom både akademin och industrin är att utveckla industriella processer som mer effektivt använder både befintliga som alternativa råvaror för produktion av viktiga kemiska intermediat. Sådana intermediat används i sin tur som råvara för att framställa funktionella och idag ovärderliga material såsom plaster, fibrer, gummin, färger, ytbehandlingsmedel m. READ MORE

  2. 2. A Study of Propane and Propene Ammoxidation over the Mo-V-Nb-Te-Oxide System

    University dissertation from Chemical Engineering, Lund University

    Author : Johan Holmberg; Lunds universitet.; Lund University.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; TEM; TPR; XPS; XRD; XANES; Chemical technology and engineering; SEM; FTIR; BET; TiO2; SiO2; Al2O3; supports; substitution; synthesis; Mo-V-Nb-Te-Ox catalysts; acrylonitrile; propene; Ammoxidation; propane; symbiosis;

    Abstract : The ammoxidation of propane is commonly regarded as being the future route for producing acrylonitrile, and the Mo-V-Nb-Te-oxide system studied here has thus far been seen as the most promising candidate for achieving this. Yields of up to 62% have been presented very elegantly in the patent literature. READ MORE

  3. 3. Degradation of acrylonitrile butadiene rubber and fluoroelastomers in rapeseed biodiesel and hydrogenated vegetable oil

    University dissertation from Stockholm, Sweden : KTH Royal Institute of Technology

    Author : Shahin Akhlaghi; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Degradation; Acrylonitrile butadiene rubber; Fluoroelastomers; Biodiesel; Hydrotreated vegetable oil; Cavitation; Bound rubber; Dehydrofluorination.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Biodiesel and hydrotreated vegetable oil (HVO) are currently viewed by the transportation sector as the most viable alternative fuels to replace petroleum-based fuels. The use of biodiesel has, however, been limited by the deteriorative effect of biodiesel on rubber parts in automobile fuel systems. READ MORE

  4. 4. A Study of Propane and Propene Ammoxidation over Antimony-Vanadium-Oxide Catalysts at Steady-State and Transient Conditions

    University dissertation from Stockholm, Sweden : KTH Royal Institute of Technology

    Author : Roland Nilsson; Lunds universitet.; Lund University.; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; oxidation; Ammoxidation; propane; propene; propylene; catalysis; transient response; antimony vanadium oxides;

    Abstract : Popular Abstract in Swedish Akrylfibrer, SAN-plast (Styren-AkrylNitril) och ABS-plast (Akrylnitril-Butadien-Styren) är tre viktiga polymerer som tex används för textilier (akrylfibrer) och optiska instrument (SAN). ABS-plast har hög motståndskraft mot kemikalier samt är slagtålig och används tex i bilar. READ MORE

  5. 5. Hemoglobin dosimetry and comparative toxicity of acrylamide and its metabolic glycidamide

    University dissertation from Stockholm : Stockholm University

    Author : Emma Bergmark; Stockholms universitet.; [1992]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Hemoglobin is a useful in vivo dosimeter for electrophilic compounds that react with nucleophilic sites in macromolecules and form covalently bound adducts. With the purpose of increasing the sensitivity of analysis of haemoglobin adducts, a method was developed for enriching adducted globin chains based on ion-exchange chromatography. READ MORE
