Abstract
Gaseous streams containing carbonyl compounds have the carbonyl content reduced by contacting the gaseous streams with a catalyst of calcium aluminate or calcium aluminate and Ca.sub.2 SiO.sub.4. Reactor effluent from an oxidative dehydrogenation reaction to produce butadiene-1,3 is contacted with calcium aluminate or calcium aluminate and Ca.sub.2 SiO.sub.4 catalyst to remove carbonyl compounds.
