Dehydrogenation Catalyst, Its Use and Method of Preparation

摘要

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.
