The object of the invention is a process and a catalyst for the dehydrogenation of alkanes, wherein the alkanes are contacted at an elevated temperature with a vanadium-containing catalyst in order to prepare alkenes. According to the invention, before the dehydrogenation reaction the catalyst is subjected to a carbon monoxide reduction, which improves the activity and selectivity of the catalyst. The catalyst may contain modification metals, for example calcium or zirconium. |
