  • SYNTHESIS OF A MOVNBTE CATALYST HAVING AN INCREASED SPECIFIC SURFACE AND HIGHER ACTIVITY FOR THE OXIDATIVE DEHYDROGENATION OF ETHANE TO ETHYLENE
    Publication number: 20200139349
    Abstract: The invention relates to a mixed oxide material comprising the elements molybdenum, vanadium, niobium and tellurium, which, when using the Cu-K? radiation, has diffraction reflections h, i, k and l in the XRD spectrum, said diffraction reflexes having their apex points at the diffraction angles (2·) 26.2°±0.5° (h), 27.0°±0.5° (i), 7.8°±0.5° (k) and 28.0°±0.5° (l), characterized in that the mixed oxide material has a pore volume of >0.1 cm3/g. The mixed oxide material according to the invention is produced by a method comprising the steps of: a) producing a mixture of starting compounds containing molybdenum, vanadium, niobium and tellurium dioxide as a tellurium-containing starting compound as well as oxalic acid and a further oxoligand selected from the group consisting of dicarboxylic acids and diols, b) hydrothermally treating the mixture of starting compounds at a temperature of 100 to 300° C.
