ABSTRACT:
Alkali metal carbonates have been found to be effective catalysts for dehydrogenation of primary and secondary alcohols. The dehydrogenated products may be either predominantly ketones and aldehydes, depending on whether the feed alcohol is secondary or primary, or may be fuel gases. Lower reaction temperatures, in the neighborhood of 600.degree. C., tend to produce high yields of liquid products. Higher temperatures encourage production of fuel gases of high calorific value. When fuel gases are a desired product, a feedstock containing water, in addition to the alcohol, produces increased yields due to the simultaneous catalysis of the water-gas shift reaction.
