Abstract: A process for preparing butadiene from n-butane by two-step dehydrogenation and removal of the residual oxygen comprised in the gas stream by means of a catalytic combustion stage which is carried out in the presence of a catalyst which comprises a monolith which comprises a catalytically inert material having a low BET surface area and a catalyst layer which has been applied to the monolith and comprises an oxidic support material, at least one noble metal selected from the group consisting of the noble metals of group VIII of the Periodic Table of the Elements, optionally tin and/or rhenium, and optionally further metals, where the thickness of the catalyst layer is from 5 to 500 μm, is described.
