Abstract

Catalysts found to be particularly effective in the dehydrogenation of alkyl aromatics, for example ethylbenzene to styrene, where the catalysts include iron oxide, 12 to 30% of an alkali metal compound, 3 to 7% of a cerium compound, 1.5 to 6.0% of a molybdenum compound and 1 to 8% of a calcium compound. Catalyst can also include 0 to 8.0% of a chromium compound.
