Abstract
Addition of small amounts of cobalt compounds to iron-chromium-potassium-vanadium oxide catalysts useful in the dehydrogenation of hydrocarbons to the corresponding more-unsaturated hydrocarbons results in an improved yield.
Claims16
A catalyst for the dehydrogenation of hydrocarbons to more unsaturated hydrocarbons comprising a mixture having:
- a. from about 35 to about 67 percent by weight of an iron oxide, measured as iron metal;
- b. from about 4 to about 25 percent by weight of a potassium compound selected from the group consisting of potassium oxide, potassium carbonate, and mixtures thereof, measured as potassium metal;
- c. from about 0.0065 to about 4.5 percent by weight of a chromium oxide, measured as chromium metal;
- d. from about 0.5 to about 3.5 percent by weight of a vanadium oxide, measured as vanadium metal, and
- e. from about 0.0075 to about 8 percent by weight of a cobalt oxide, measured as cobalt metal.
