Abstract

En ruthenium på alumina-katalysator omfattende minst én rutheniumkomponent båret på et porøst a-aluminamateriale. Katalysatoren har et spesifikt overflateareal (S) på 7-50 m/g, og et forhold S/Smellom spesifikt overflateareal på ruthenium på alumina-katalysatoren (S) og overflatearealet på det porøse a-aluminamateriale (S) i området 3-50. Katalysatoren har en mikroporestruktur med en distribusjonsprofil av porediameteren slik at minst én topp faller innen området 5-1000 Å. Katalysatoren ifølge oppfinnelsen har utmerket knusefasthet og høy aktivitet pr. enhet rutheniumvekt. Videre har katalysatoren bemerkelsesverdig varmebestandighet, og den opprettholder sin høye aktivitet selv ved høye temperaturer under reaksjon og brenning.A ruthenium on alumina catalyst comprising at least one ruthenium component supported on a porous α-alumina material. The catalyst has a specific surface area (S) of 7-50 m 2 / g, and a ratio S / Between the specific surface area of ruthenium on the alumina catalyst (S) and the surface area of the porous α-alumina material (S) in the range 3-50. The catalyst has a micropore structure with a distribution profile of the pore diameter so that at least one peak falls within the range 5-1000 Å. The catalyst according to the invention has excellent crush strength and high activity per. unit ruthenium weight. Furthermore, the catalyst has remarkable heat resistance, and it maintains its high activity even at high temperatures during reaction and combustion.
