Abstract: A novel steam reforming catalyst comprising hibonite and potassium beta-alumina with improved resilience, improved activity, reduced potassium leaching and reduced coking problems. It also regards a method for producing the novel catalyst and uses of the novel catalyst in reforming reactors, in a plant for producing hydrogen gas, or in a plant for producing synthesis gas, or as a guard bed in a steam reforming process.

Abstract: A process for producing a catalyst, comprising the steps of modifying a carrier by a first impregnation with at least one alkaline earth metal in a first metal precursor solution, the first metal precursor being decomposed to form at least one metal oxide or metal hydroxide, thereby obtaining a modified carrier. A second impregnation is carried out by incipient wetness by a second precursor solution comprising at least one metal Me in a second solution. Finally, the second precursor is decomposed, thereby obtaining a catalyst body having an enrichment of the at least one metal Me in the outer shell of the catalyst body, the metal being present in a concentration having either as an egg-shell profile or a hammock profile.
