ABSTRACT:
A method for dehydrogenating dehydrogenatable hydrocarbons which comprises contacting said hydrocarbons with an oxide of Pr 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 Pr are regenerated by oxidizing the reduced composition with oxygen. Solids prepared from the oxide Pr.sub.6 O.sub.11 are particularly effective in the process.
