Beschreibung
Zusammenfassung:	A regenerative process for the preparation of olefinically unsaturated compounds by oxidation/dehydrogenation of selectively oxidizable hydrocarbons over an oxygen carrier acting as catalyst, in the absence of molecular oxygen, alternating (in repeated cycles) with regeneration of the spent oxygen carrier with a gaseous molecular oxidizing agent, in which the spent (reduced) catalyst is cooled, prior to introduction of the regenerating gas, to a temperature which is below the temperature of the reaction, regeneration being controlled in such a manner that the highest temperature occurring during regeneration does not exceed the temperature of reaction at which dehydrogenation is commenced.
