Abstract of the Disclosure Novel compositions of matter include: mixed oxides of (a) at least one oxide of chromium, at least one oxide of manganese and at least one oxide of magnesium, Lanthanum Series metals, preferably lanthanum and cerium, and/or niobium; (b) at least one oxide of chromium, at least one oxide of calcium, strontium, tin and/or antimony, at least one oxide of manganese and at least one oxide of magnesium, Lanthanum Series metals and/or niobium; (c) at least one oxide of chromium, at least one oxide of iron and at least one oxide of magnesium, Lanthanum Series metals and/or niobium; and (d) at least one oxide of chromium, at least one oxide of iron, at least one oxide of manganese and at least one oxide of magnesium, Lanthanum Series metals and/or niobium. These compositions are particularly effective as catalyst compositions for the conversion of C3 and C4 hydrocarbons to less saturated hydrocarbons, with high selectivities to ethylene and ethane and particularly ethylene, and the addition of the chromium significantly extends the activity of the catalyst for such selective conversion before regeneration is necessary. A method of converting C3 and C4 hydrocarbons to less saturated hydrocarbons, and selectively to ethylene and ethane and particularly ethylene, is also disclosed. Carrying out the process in the presence of steam is essential to the process when the catalyst contains iron and is optional when the catalyst does not contain iron. Limiting the amount of bound or fixed sulfur in the catalyst also improves the catalyst.
