A dehydrogenation catalyst is formed by forming a mixture comprising a bayerite aluminum hydroxide (Al(OH)), a lanthanum (La) source, a cerium (Ce) source, a barium (Ba) source, a zirconium (Zr) source, and water into a shaped body. The shaped body is calcined at a temperature of at least 750&#xb0; C. to form a catalyst support. The catalyst support is treated with a dehydrogenation catalyst component to form a treated catalyst support containing the dehydrogenation catalyst component. The treated catalyst support is then calcined. The resulting catalyst composition may be used by contacting a paraffin hydrocarbon feed with a catalyst within a reactor in the presence of steam under dehydrogenation reaction conditions suitable to form dehydrogenated hydrocarbon products.

Dehydrogenation catalyst, its use and method of preparation

A method of forming a dehydrogenation catalyst support is carried out by forming a mixture comprising a bayerite aluminum hydroxide (Al(OH)) and water into a support material. The support material is particulized. The particulized support material is compressed to a pressure of at least 5,000 psig to form a shaped body. The shaped body is calcined in pure steam at a temperature of at least 750&#xb0; C. for at least 0.25 hours to form a catalyst support having an average pore diameter of 200 &#x212b; or greater. The catalyst support can then be treated with a dehydrogenation catalyst component so that the catalyst support contains the dehydrogenation catalyst component to form a dehydrogenation catalyst that can then be used by contacting a hydrocarbon feed with the catalyst within a reactor in the presence of steam under dehydrogenation reaction conditions suitable to form dehydrogenated hydrocarbon products.
