    Abstract : The environmental concerns in recent times have grown especially after signing Montreal protocol. In the last ten years, researchers have focussed mainly on understanding the boiling and condensation phenomena of HFC refrigerants in minichannels. READ MORE

  3. 3. 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

    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. Studies of partial oxidation and combustion over heterogeneous catalysis by transient experiments

    University dissertation from Secretary, Dept. of Chem. Eng. II, P.O. Box 124, SE-22100 Lund

    Author : Andreas Hinz; Lunds universitet.; Lund University.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catalytic combustion; Selective Oxidation; Sulphur dioxide; Ammonia; Methanol; Propane; Metal catalysts; Metal oxide catalysts; Transients; Simulation; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Carbochemistry; petrochemistry; fuels and explosives technology; Petrokemi; bränslen; sprängämnen;

    Abstract : Transient experiments are one of many techniques available to study heterogeneous catalysis and the catalysts used. The results obtained by transient experiments contain valuable information that is helpful in explaining reaction mechanism and interaction at the catalytic surface. READ MORE
