A process for converting propane to ethylene over ZSM-50. The ZSM-50 may be contacted with an anhydrous acidic oxide gas capable of accepting hydrogen by reacting therewith such as sulfur, dioxide (SO2), to enhance the ethylene selectivity of the conversion. The zeolite may be pretreated with acidic oxide gas or contacted in situ by cofeeding the acidic oxide gas with the propane. High ethylene selectivity is achieved.
