ABSTRACT:
There is provided a process for converting propane to ethylene over a zeolite catalyst comprising ZSM-50. This zeolite may be contacted with an anhydrous acidic oxide gas capable of accepting hydrogen by reacting therewith, such as sulfur dioxide (SO.sub.2), in order to enhance the ethylene selectivity of the conversion. The zeolite may either be pretreated with this acidic oxide gas or contacted in situ by cofeeding the acidic oxide gas along with the propane reactant. Particularly in view of the tendency of zeolites such as ZSM-5 to further convert olefins produced into aromatics and other hydrocarbons, the large degree of ethylene selectivity achieved by the process of the present invention is surprising.
