The catalytic stability of LiCl/MnO x /PC catalyst have been investigated, the deactivation mechanism was discussed. The experimental results show that ethane conversion decreases and ethylene selectivity keeps about 90% as reaction time increases. The main deactivation reasons of LiCl/MnO x /PC catalyst for oxidative dehydrogenation of ethane (ODHE) to ethylene are the transition of active species Mn 2 O 3 to MnO species and the loss of active component Cl in catalyst. Instead of ethane with FCC tailed‐gas, the stability of LiCl/MnO x /PC catalyst has been largely improved.
