[54] METHOD OF PREPARING AN ALUMINA CATALYST SUPPORT AND CATALYST FOR DEHYDROGENATION REACTIONS, AND ITS USE
[57] 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.
