SUAREZ, M. Natalia  and  RIOS, Luis A.. Deshidrogenación oxidativa de propano con Na2O sobre zeolita Cr/FeZSM-5 . Ing. compet. [online]. 2013, vol.15, n.1, pp.63-70. ISSN 0123-3033.

The catalytic activity of FeZSM-5 impregnated with Cr was studied in the propane oxidative dehydrogenation, using N2O as oxidant. For the metal impregnation, the methods spray-drying and wet-impregnation were evaluated, to determine the effect on metal dispersion and catalytic activity. The catalysts were characterized by x-ray diffraction, thermogravimetric analysis and surface area by N2 adsorption. The highest yield (15.2%) was obtained at 400°C with the catalyst containing 0.5% Cr through wet impregnation. The catalysts showed a very high stability
