  1. 1. 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 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

  4. 4. 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]
