Title (EN) CATALYST REGENERATION
(FR) RÉGÉNÉRATION DE CATALYSEURS
Abstract:
(EN) A method is disclosed for regenerating regenerating a used catalyst mixture comprising (i) an isomerization catalyst comprising magnesium oxide and (ii) a metathesis catalyst comprising an inorganic carrier and at least one of molybdenum oxide and tungsten oxide. The method comprises (a) decoking the used catalyst mixture in the presence of an oxygen-containing gas to produce a decoked catalyst mixture; and (b) contacting the decoked catalyst mixture with steam at a temperature in the range of 100 to 300°C to produce a regenerated catalyst mixture.
(FR) La présente invention concerne un procédé de régénération d'un mélange de catalyseurs épuisés comprenant (i) un catalyseur d'isomérisation à base d'oxyde de magnésium et (ii) un catalyseur de métathèse comprenant un support inorganique et de l'oxyde de molybdène et/ou de tungstène. Le procédé consiste à (a) décoker le mélange de catalyseurs épuisés en présence d'un gaz contenant de l'oxygène pour obtenir un mélange de catalyseurs décokés, et (b) mettre ce mélange de catalyseurs décokés en contact avec de la vapeur d'eau à une température comprise entre 100 et 300 °C pour obtenir un mélange de catalyseurs régénérés.
