Abstract
(EN)
One embodiment of the present application provides a method for producing butadiene, the method including a step for introducing reactants, including butene, oxygen, nitrogen, and steam, into a reactor filled with a catalyst, and thereby causing an oxidative dehydrogenation reaction, wherein during the initial start-up of the oxidative dehydrogenation reaction, the oxygen is introduced into the reactor before butene, or the oxygen is introduced into the reactor at the same time as butene.
(FR)
La présente invention concerne, dans un mode de réalisation, un procédé de production de butadiène, le procédé comprenant une étape d’introduction de réactifs, comprenant du butène, de l’oxygène, de l’azote, et de la vapeur, dans un réacteur chargé d’un catalyseur, ce qui amène une réaction de déshydrogénation oxydative, où durant le démarrage initial de la réaction de déshydrogénation oxydative, de l’oxygène est introduit dans le réacteur avant le butène, ou de l’oxygène est introduit dans le réacteur en même temps que le butène.
