Summary:One embodiment of the present application relates to a method for producing 1,3-butadiene, including a step of inducing an oxidative dehydrogenation reaction of reactants containing butene and oxygen in the presence of a catalyst. The production method of 1,3-butadiene is performed using three reactors, wherein two of the three reactors are applied in a series-connected reaction mode, and the other one is applied in a regeneration mode. The reaction mode and the regeneration mode are simultaneously performed, wherein in the reaction mode, an oxidative dehydrogenation reaction of reactants containing butene is performed, and in the regeneration mode, a process of regenerating a deactivated catalyst is performed. 본 출원의 일 실시상태는, 부텐을 포함하는 반응물 및 산소를 촉매의 존재 하에 산화적 탈수소화 반응시키는 공정을 포함하는 1,3-부타디엔의 제조방법이고, 상기 1,3-부타디엔의 제조방법은 3개의 반응기를 이용하여 수행되며, 상기 3개의 반응기 중 2개의 반응기는 직렬연결된 반응모드로 적용되고, 나머지 1개의 반응기는 재생모드로 적용되며, 상기 반응모드와 재생모드는 동시에 수행되고, 상기 반응모드에서는 부텐을 포함하는 반응물의 산화적 탈수소화 반응이 수행되며, 상기 재생모드에서는 비활성화가 진행된 촉매를 재생시키는 공정이 수행되는 것인 1,3-부타디엔의 제조방법을 제공한다.
