Abstract: Hydrocarbons are dehydrogenated with a mixed oxide catalyst which is prepd. by drying and calcing a mixture of Fe2O3 20-95, K2O or K2CO3 3-30, V2O5 0.01-9, MoO3 r WO3 0.01-20, CeO3 0/01-50, CoO 0-50 and Cr2O3 0-30 wt. %. Thus, ethylbenzene is dehydrogenated at 610≦̸C, and 0-374 atm. with catalyst and water vapor to give styrene with selectivity of 93.8.

Abstract: A catalyst for the dehydrogenation of hydrocarbons to more unsaturated hydrocarbons comprising:(a) from 50 to 95 percent by weight of an iron oxide, measured as ferric oxide;(b) from 5 to 30 percent by weight of potassium oxide and/or potassium carbonate, measured as potassium oxide;(c) from 0.01 to 9 percent by weight of a vanadium oxide, measured as vanadium pentoxide;(d) from 0.01 to 10 percent by weight of an additive metal oxide selected from the group consisting of aluminium, cadmium, copper, magnesium, manganese, nickel, a member of a rare earth series, uranium, zinc and mixtures thereof, measured as the individual oxide having the most stable form in air at one atmosphere and 25.degree.C, and(e) from 0 to 30 percent by weight of a chromium oxide, measured as chromic oxide.
