Introduction The global demand for light olefins is increasing and efforts are being devoted to the conversion of lower alkanes (C 3 –C 4 ) to respective olefins. Oxidative dehydrogenation (OXDH) of alkanes is considered as a

Introduction In recent years, oxidative dehydrogenation of propane (ODP) has been intensively investigated because of its significant advantages over the dehydrogenation process, which is presently utilized for producing alkene

Abstract  

NiMoO4 obtained by calcination of precursors has been shown to be a very effective catalyst for oxidative dehydrogenation of propane into propene. Preparation conditions and thermal decomposition of two precursors have been studied by TG-DTA, HTXRD, FFT-IR, and thermo-desorption coupled to mass spectroscopy in order to determine their composition and to define the best treatment to favour the oxidative dehydrogenation process. The selectivity and activity for propane transformation into propene are very different depending on the nature of the precursor and of the active phases obtained after thermal activation. The more selective high-temperature β phase of NiMoO4 has been obtained at a lower temperature (500°C) than previously reported (700°C).

Open access

oxidative dehydrogenation is an effective way to increase the conversion and/or lower the reaction temperature [ 1 ]; however, the desirable dehydrogenation product is vulnerable by deep oxidation when using oxygen as the oxidant [ 2 ]. Many

phases with the lyonsite-type structure catalyze oxidative dehydrogenation of propane [ 14 ]. Investigation of phase formation in the system CuO–V 2 O 5 –Fe 2 O 3 and their properties are therefore interesting not only because of the cognitive value of
