The influence of the oxidative dehydrogenation of butene-1 on the phase composition of the nickel ferrite/γ-Al2O3 catalyst

The influence of the oxidative dehydrogenation of butene-1 on the phase composition of a ferrite-containing catalyst on γ-Al2O 3 with a Ni: Fe atomic ratio of 1: 4 was studied. It was found by X-ray diffraction, EPR, IR absorption spectroscopy, and derivatography that the reduction of Fe3+ to Fe2+ with the formation of The Fe3O4 magnetite phase occurred under various conditions of olefin (reaction mixture)-catalyst surface contact. The treatment of the catalyst with the reaction mixture and its oxidation decrease the degree of spinel phase imperfection. © Nauka/Interperiodica 2006.
