Claims
- 1. A process for converting propane to ethylene, said process comprising contacting said propane with a catalyst comprising a crystalline aluminosilicate zeolite ZSM- 50 having x-ray diffraction pattern as set forth in Table 1 under conditions sufficient to effect said propane to ethylene conversion.
- 2. A process according to claim 1, wherein said catalyst further comprises a binder for said ZSM-50.
- 3. A process according to claim 1, wherein said conversion conditions comprise a temperature of from about 100.degree. C. to about 700.degree. C., a pressure of from about 0.1 atmosphere to about 60 atmospheres, and a weighty hourly space velocity of from about 0.5 to about 400.
- 4. A process for converting propane to ethylene, said process comprising contacting said propane with a catalyst comprising a crystalline aluminosilicate zeolite ZSM-50 having x-ray diffraction pattern as set forth in Table 1 under conditions sufficient to effect said propane to ethylene conversion wherein an anhydrous acid oxide gas capable of accepting hydrogen by reacting therewith is also cofed with said propane for contact with said catalyst, the amount of said acidic oxide cofeed being sufficient to further increase the yield of ethylene produced from said propane.
- 5. A process according to claim 1, wherein said catalyst further comprises a binder for said ZSM-50.
- 6. A process according to claim 4, wherein said conversion conditions comprise a temperature of from about 100.degree. C. to about 700.degree. C., a pressure of from about 0.1 atmosphere to about 60 atmospheres, and a weight hourly space velocity of from about 0.5 to about 400.
- 7. A process according to claim 4, wherein said acidic oxide gas is sulfur dioxide.
