ABSTRACT:
A method for dehydrogenating dehydrogenatable hydrocarbons which comprises contacting said hydrocarbon with an oxide of Ru 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 preferably carried at about 500.degree. to 1000.degree. C. Reducible oxides of Ru are regenerated by oxidizing the reduced composition wth oxygen. Bulk ruthenium oxides promoted by sodium and/or compounds thereof are particularly preferred contact solids.
