    The Feasibility of Ni-alumina Catalysts in Oxidative Dehydrogenation of Ethane

  • Original language description

    The contribution deals with the development on the efficient Ni-alumina catalyst for the oxidative dehydrogenation (ODH) of ethane to ethene. The performance of Ni-alumina catalysts with varying nickel loadings and with thermal pretreatment was studied.We contribute to the understanding of the relationship between the activity of nickel species in ODH of ethane and its distribution. To analyze this effect, Ni-alumina catalysts were analyzed by UV-Vis spectroscopy, and H2-TPR profile. Ni-alumina catalysts were highly active and selective (ca 80 %) in the ODH of ethane. The catalysts contained both tetrahedral and octahedral nickel species, suggesting that nickel aluminate represented a partial spinel, where Ni(II) ions occupy both octahedral and tetrahedral sites of the oxygen lattice. It was suggested that the octahedral nickel species were more active than the tetrahedral ones.

    Potenciál Ni-alumina katalyzátorů v oxidativní dehydrogenaci ethanu

  • Czech description

    Příspěvek se zabývá vývojem efektivního Ni-alumina katalyzátoru pro oxidativní dehydrogenaci ethanu na ethen. Aktivita Ni-alumina katalyzátoru byla studována pro materiály s různým obsahem niklu a při různém teplotním opracování katalyzátorů. Práce přispěla k pochopení vztahu mezi distribucí Ni - částic a jejich aktivitou v ODH ethanu. Pro studii tohoto efektu byla využita UV-Vis spektroskopie a H2-TPR profil. Ni-alumina katalyzátory byly vysoce aktivní a selektivní (cca 80 %) v uvedené reakci. Katalyzátory obsahovaly Td a Oh koordinované částice Ni, přičemž bylo navrženo, že Oh koordinované částice jsou více aktivní.
