EFECTO DEL VANADIO EN CATALIZADORES DERIVADOS DE MATERIALES TIPO HIDROTALCITA EN DESHIDROGENACIóN OXIDATIVA DE PROPANO

two novel hydrotalcite-like materials have been synthesized by hydrothermal treatment. using ionic exchange method, the materials have been modified with vanadium species. characterization of the materials was carried out by x-ray diffraction (xrd), chemical analyses (atomic absorption), and thermogravimetric analyses (tga). modified and non-modified materials have been calcined in order to obtain respective mixed oxides, which were tested in oxidative dehydrogenation of propane (odhp) at a space velocity of 50 ml/min g with a temperature range between 250-500 °c. the catalytic studies showed a positive effect by incorporating vanadium for nicocr system, while for the nicofe modified system a decrease in catalytic activity was shown.
