ABSTRACT Feasibility and energy analysis of chemical looping oxidative dehydrogenation of propane (CL-ODHP) process is performed by thermodynamic method. Results show that Mn2O3/MnO can be used for CL-ODHP, after one redox looping, about 100 kJ/mol energy can be generated. Energy analysis indicates that the process requires 8432.82 kJ/kgpropene external fuel input at reaction temperatures with commercial propane conversion and propene selectivity. And process energy consumption decreases with decreasing of dehydrogenation and regeneration temperatures and increasing of propane conversion and propene selectivity. Recovering waste heat of hot streams from two reactors can cut by nearly 45% energy consumption of the process.
