Abstract:
A non-oxidative dehydrogenation catalyst for dehydrogenating a hydrocarbon feed stream in a hydrocarbon reactin zone, wherein the components of the hydrocarbon feed stream in the reaction zone consist essentially of an alkylaromatic hydrocarbon and steam, wherein the composition of the catalyst comprises about 30 to about 90 weight percent of an iron compound calculated as an Fe.sub.2 O.sub.3, about 1 to about 50 weight percent of an alkali metal source calculated as an alkali metal oxide, about 0.1 ppm to about 1000 ppm of a noble metal source selected from the group consisting of elemental noble metals, compounds containing noble metals and combinations thereof, wherein all weight percents are based on the total weight of the catalyst.
