| titleOfInvention | METHOD OF OBTAINING BUTADIENE FROM n-BUTANE |
| abstract | A method for producing butadiene from n-butane, comprising the following stages: A) preparation of the initial gas stream a containing n-butane; B) feeding a feed gas stream a containing n-butane to at least the first dehydrogenation zone and non-oxidative catalytic dehydrogenation of n-butane, whereby a product gas stream b containing n-butane, 1-butene, 2-butene, butadiene is obtained, hydrogen, low-boiling impurities, under certain conditions carbon oxides and, under certain conditions, water vapor; C) supplying a nonoxidative catalytic dehydrogenation product gas stream b and an oxygen-containing gas to at least the second dehydrogenation zone and oxidative dehydrogenation of n-butane, 1-butene and 2-butene, whereby a product gas stream c containing n-butane is obtained, 2 -butene, butadiene, low boiling impurities, carbon oxides and water vapor, with a higher butadiene content than in the product gas stream b; D) separating low-boiling impurities and water vapor, whereby a C-product gas stream d is obtained, mainly consisting of n-butane, 2-butene and butadiene; E) separation by extractive rectification of the C-product gas stream d into a stream el, consisting mainly of n-butane and 2-butene, and a valuable product stream e2, mainly consisting of butadiene; F) return flow el to the first dehydrogenation zone. |
