Document Type and Number:

WIPO Patent Application WO/2021/172239

Kind Code:

A1

Abstract:

This method for producing 1, 3-butadiene has: a step A in which oxygen and a feedstock gas that includes n–butene are supplied from a lower section of a reaction container comprising a metal atom-containing catalyst, to the reaction container, and a product gas including 1, 3-butadiene is obtained by means of oxidative dehydrogenation of the n-butene; a step B in which the product gas including 1, 3-butadiene is cooled; and a step C in which 1, 3-butadiene is separated from the cooled product gas including 1, 3-butadiene, by selective absorption into an absorption solvent.
