Abstract
Improved oxidative dehydrogenation catalysts are prepared by modifying a zinc ferrite oxidative dehydrogenation catalyst with manganese oxide. The resulting catalyst compositions exhibit higher conversions and yields.
Claims7
In the process of oxidative dehydrogenation of organic compounds having from about 2 to 20 carbon atoms and at least one ##STR2## group in the presence of a catalyst composition at a temperature of from about 500.degree. F to about 1,200.degree. F and in the presence of from about 0.2 to about 2.0 mols of oxygen per mole organic compound to thereby produce a dehydrogenated compound having the same number of carbon atoms, wherein the improvement comprises said catalyst consisting of (1) a zinc ferrite composition having the empirical formula
- Zn.sub.x Fe.sub.y O.sub.z
- wherein x is from about 0.1 to about 2, y is from 0.3 to about 12, and z is from about 3 to 18 and (2) additionally containing free manganese oxide as a promoter in an amount from about 0.1 to about 10 weight percent based on the weight of the zinc ferrite composition.
