Microwave Assisted Combustion Synthesis of Li/MgO Nanocatalyst with Various Fuel Ratios Used in Production of Ethylene from Ethane

The Li/MgO nanocatalyst with different fuel to oxidant ratio were synthesised by microwave inducedcombustion method. The activity of prepared catalysts was evaluated for oxidative dehydrogenation of ethane. Thesamples were characterized by techniques including XRD and FESEM. The FESEM results showed spongy structurefor catalyst synthesized via combustion also from FESEM micrographs it is obvious by decreasing the F/O the particlesize of prepared catalysts increased while the homogeneity of catalysts structure increased. The XRD results showedwell dispersion of Li2O on the all samples. GC results showed that optimum F/O ratio for the ethane oxidativedehydrogenation over Li/MgO with 3% loading of Li. is stoichiometric ratio.
