Abstract
Disclosed are shaped dehydrogenation catalysts, methods for making the catalysts, and methods for dehydrogenating a hydrocarbon using the catalyst. A method for making the shaped dehydrogenation catalyst can include combining a group 13 metal precursor and a group 1 metal precursor with a catalyst support precursor to form a shapeable material, shaping the shapeable material to form a wet shaped material, drying the wet shaped material to form a dry shaped material, and calcining the dry shaped material to form the shaped dehydrogenation catalyst.

A method for making a shaped dehydrogenation catalyst, the method comprising:
- (a) combining a group 13 metal precursor and a group 1 metal precursor with a catalyst support precursor, to form a shapeable material;
- (b) shaping the shapeable material to form a wet shaped material;
- (c) drying the wet shaped material to form a dry shaped material;
- and
- (d) calcining the dry shaped material to form the shaped dehydrogenation catalyst;
- wherein the shaped dehydrogenation catalyst comprises particles with an average radial crush strength greater than 0.5 daN/mm.
A method for making a shaped dehydrogenation catalyst, wherein the shaped dehydrogenation catalyst comprises:
- 1 wt. % to 20 wt. % Ga2O3, 0.1 wt. % to 3 wt. % group 1 metal oxide, 0.002 wt. % to 0.025 wt. % PtO2 and a catalyst support selected from the group consisting of alumina, silica, zirconia, titania, or any combination thereof,
- the method comprising:
- (a) combining a gallium oxide precursor and a group 1 metal precursor with a catalyst support precursor selected from the group consisting of aluminum hydroxide, zirconium hydroxide, titanium hydroxide, silicon hydroxide, or any combination thereof, to form a shapeable material;
- (b) shaping the shapeable material to form a wet shaped material;
- (c) drying the wet shaped material to form a dry shaped material;
- and
- (d) calcining the dry shaped material to form the shaped dehydrogenation catalyst, wherein in step (b) the shapeable material is shaped by an extrusion process, a spheronization process, or a combination thereof, and wherein the shaped dehydrogenation catalyst comprises particles with an average radial crush strength greater than 0.5 daN/mm, and/or wherein the dry shaped material is calcined at a temperature from 700° C. to 950° C.
