Abstract
The invention discloses a binder-free high strength and low steam-to-oil ratio ethylbenzene dehydrogenation catalyst, which is characterized by comprising the following components in percentage by weight: (a) 60-85% Fe2O3; (b) 3-25% K2O; (c) 0.1-5% MoO3; (d) 3-20% CeO2; (e) 0.1-5% CaO; (f) 0.1-5% Na2O; (g) 0.1-5% MnO2, wherein the weight ratio of sodium oxide to manganese dioxide is 0.1-10, and no binder is added during the preparation of the catalyst. The low steam-to-oil ratio ethylbenzene dehydrogenation catalyst provided by the present invention contains no binder and maintains high strength, and has high activity and stability at low steam-to-oil ratio.
