Abstract: | The catalytic performances of Mn-based catalysts have been investigated for the oxidative dehydrogenation of both ethane (ODE)
and propane (ODP). The results show that a LiCl/MnOx/PC (Portland cement) catalyst has an excellent catalytic performance for oxidative dehydrogenation of both ethane and propane
to ethylene and propylene, more than 60% alkanes conversion and more than 80% olefins selectivity could be achieved at 650°C.
In addition, the results indicate that Mn-based catalysts belong to p-type semiconductors, the electrical conductivity of
which is the main factor in influencing the olefins selectivity. Lithium, chlorine and PC in the LiCl/MnOx/PC catalyst are all necessary components to keep the excellent catalytic performance at a low temperature.
