ABSTRACT:
A method for dehydrogenating dehydrogenatable hydrocarbons which comprises contacting hydrocarbon with an oxide of Tb having combined therewith an amount of alkali and/or alkaline earth metal which is sufficient to improve the selectivity to dehydrogenated hydrocarbon products. The oxide is reduced by the contact which is carried at about 500.degree. to 1000.degree. C. Reducible oxides of Tb are regenerated by oxidizing the reduced composition with molecular oxygen. Solids prepared from the oxide Tb.sub.4 O.sub.7 are particularly effective in the process.
