  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; [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
