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% Fe 2 O 3 ; (b) 3-25% K 2 O; (c) 0.1-5% MoO 3 ; (d) 3-20% CeO 2 ; (e) 0.1-5% CaO; (f) 0.1-5% Na 2 O; (g) 0.1-5% MnO 2 , wherein the weight ratio of sodium oxide to manganese dioxide is 0.1-10; (h) 0.1-100 ppm of at least one element or oxide of Pb, Pt, Pd, Ag, Au, Sn; 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.

Claim (Index 2):
The binder free high strength, low steam-to-oil ratio ethylbenzene dehydrogenation catalyst according to  claim 1 , wherein the weight ratio of Na 2 O and MnO 2  is 0.2-8.
