Abstract: A dehydrogenation catalyst is formed by forming a mixture comprising a bayerite aluminum hydroxide (Al(OH)3), 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° 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.

Abstract: A method of forming a dehydrogenation catalyst support is carried out by forming a mixture comprising a bayerite aluminum hydroxide (Al(OH)3) 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° C. for at least 0.25 hours to form a catalyst support having an average pore diameter of 200 ? 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.

Abstract: A catalyst composition useful for the dehydrogenation of hydrocarbon comprises components (A)-(G). Component (A) is a catalyst substrate. (B) is platinum. (C) is at least one of germanium, tin, lead, gallium, indium, and titanium. (D) is phosphorus, the total amount of component (D) being at a level of from 1 wt. % to 3 wt. %. (E) is at least one of magnesium, calcium, strontium, barium, radium, and a lanthanide, the total amount of component (E) being at a level of from 0.1 wt. % to 5 wt. %. (F) is chloride at a level of 0.1 wt. % to 2 wt. %. Component (G) is manganese. The catalyst may be used in the conversion of hydrocarbons wherein a hydrocarbon feed is contacted with the catalyst within a reactor under hydrocarbon conversion reaction conditions to form hydrocarbon conversion products. Sources of the various components are combined in a method to form the catalyst composition.

Abstract: A catalyst component formed by the steps of contacting a transition metal-containing metallocene of a transition metal of Group 4, 5 or 6 of the Periodic Table of the Elements with silica or an organic support. This product is contacted with an organomagnesium compound or complex followed by contact with an alcohol and a silane. Finally, the so-contacted product is contacted with a Group 4, 5 or. 6 transition metal-containing non-metallocene compound. The component is preferably combined with an aluminum-containing cocatalyst to form a catalyst system.
