Zusammenfassung:The present invention relates to a process for nonoxidative dehydroaromatization of aliphatic hydrocarbons by converting a reactant stream comprising aliphatic hydrocarbons in the presence of a catalyst which comprises at least one metallosilicate as a support, at least one element selected from the group of Mo, W and Re as an active component and at least one further transition metal which is not a noble metal as a dopant, wherein the catalyst is regenerated regularly with hydrogen under nonoxidative conditions. The further transition metal used is preferably Fe, Ni, Cu and Co.
