    Two series of Zn-ZSM-5 catalysts were prepared by ion exchanging two commercial zeolites with different Si/Al ratios (40 and 15) with increasing Zn loadings. The nature of the Zn sites in the zeolite was studied by ...
  • Del Campo, Pablo; Olsbye, Unni; Lillerud, Karl Petter; Svelle, Stian; Beato, Pablo (Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)
    In the present study, a series of H-ZSM-22 mesoporous catalysts resulting from three different desilication treatments (NaOH treatment, treatment using mixtures of NaOH/CTAB and using mixtures of NaOH/TBAOH) and sequential ...
  • Pappas, Dimitrios; Borfecchia, Elisa; Dyballa, Michael Martin; Pankin, Ilia A.; Lomachenko, Kirill A.; Martini, Andrea; Signorile, Matteo; Teketel, Shewangizaw; Arstad, Bjørnar; Berlier, Gloria; Lamberti, Carlo; Bordiga, Silvia; Olsbye, Unni; Lillerud, Karl Petter; Svelle, Stian; Beato, Pablo (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Cu-exchanged zeolites possess active sites that are able to cleave the C–H bond of methane at temperatures ≤200 °C, enabling its selective partial oxidation to methanol. Herein we explore this process over Cu-SSZ-13 ...
