  • Acidity effect on benzene methylation kinetics over substituted H-MeAlPO-5 catalysts 
    Mortén, Magnus; Cordero Lanzac, Tomas; Cnudde, Pieter; Redekop, Evgeniy; Svelle, Stian; Van Speybroeck, Veronique; Olsbye, Unni (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Methylation of aromatic compounds is a key reaction step in various industrial processes such as the aromatic cycle of methanol-to-hydrocarbons chemistry. The study of isolated methylation reactions and of the influence ...
  • Collective action of water molecules in zeolite dealumination 
    Nielsen, Malte; Hafreager, Anders; Brogaard, Rasmus Yding; De Wispelaere, Kristof; Falsig, Hanne; Beato, Pablo; Van Speybroeck, Veronique; Svelle, Stian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    When exposed to steam, zeolite catalysts are irreversibly deactivated by loss of acidity and framework degradation caused by dealumination. Steaming typically occurs at elevated temperatures, making it challenging to ...
  • Experimental and theoretical evidence for promotional effect of acid sites on the diffusion of alkenes through small-pore zeolites 
    Cnudde, Pieter; Redekop, Evgeniy; Dai, Weili; Porcaro, Natale G.; Waroquier, Michel; Bordiga, Silvia; Hunger, Michael; Li, Landong; Olsbye, Unni; Van Speybroeck, Veronique (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The diffusion of saturated and unsaturated hydrocarbons is of fundamental importance for many zeolite-catalyzed processes. Transport of small alkenes in the confined zeolite pores can become hindered, resulting in a ...
