Synthesis and Characterization of Nax/Ni Zeolite Nanocatalyst and Their Application in the Process of Oxidative Dehydrogenation Propanol

Abstract

Catalyst samples were synthesized by the method of impregnation on the basis of NaX zeolite and Ni metal and their activity was studied in the oxidation process of n-propanol in the temperature range of 423-723K. It has been established that the conversion rate of alcohol and the yield of reaction products on the modified samples increase significantly compared to the original NaX sample. According to the results of the research, it was found that if the reactions of intramolecular and intermolecular dehydration of alcohol predominate at relatively low temperatures, then the reactions of its partial and complete oxidation are accelerated at high temperatures. It was determined that the method of modifying the original NaX zeolite makes it possible to optimize the phase composition of the synthesized catalyst and the size of the active component, which allows to adjust the yield of the main reaction products and reduce the temperature limit of the reaction. As a result of the study, it was found that the average size of NiO particles included in the structure of NaX zeolite is 28314 nm. This suggests that the size of NiO particles in the zeolite structure is at the nanoparticle level.
