ABSTRACT:
Compositions of matter comprise oxides of silicon, aluminum and/or titanium mixed with combinations of manganese oxide and magnesium oxide; iron oxide and magnesium oxide; calcium, strontium, barium, tin and/or antimony oxides, manganese oxide and magnesium oxide; and iron oxide, manganese oxide and magnesium oxide. These compositions are particularly useful as catalysts for selectively converting propane and butanes to ethylene and ethane and particularly to ethylene. A method for converting propane and butanes to less saturated hydrocarbons is also disclosed in which the catalyst life is extended and the selectivity to ethylene and ethane, particularly ethylene, is improved by carrying out the contacting with the catalyst in the presence of steam, when the catalyst contains an oxide of iron and, optionally, when the catalyst does not contain an oxide of iron.
