Title (EN) METHOD OF REGENERATION OF RHODIUM-CONTAINING CATALYST
(FR) METHODE DE REGENERATION D"UN CATALYSEUR CONTENANT DU RHODIUM
Abstract: front page image
(EN)A method of regeneration of rhodium-containing catalysts, deactivated and poisoned with sulphur in the course of dealkylation of alkylbenzols or their technical mixtures with steam or hydrogen, comprising stages of coke firing in an oxygen-containing gas and of chlorination with chlorine or a chloroorganic combination in the flow of hydrogen, an inert gas or an inert gas mixed with oxygen and moisture. The catalyst is additionally treated with ammonia or nitrogen-containing compound, capable, under the treatment conditions, of desintegrating and creating ammonia, in the presence of at least one of the components selected from the following group: water, hydrogen, nitrogen-oxygen mixture. The treatment can be carried out both in liquid and gaseous phases at a temperature of 20 to 650 C and under a pressure of 1 to 50 atm.
(FR)Une methode de regeneration de catalyseurs contenant du rhodium, desactives et empoisonnes par le soufre pendant la desalkylation d"alkylbenzoles ou de leurs melanges techniques avec de la vapeur ou de l"hydrogene, consiste a chauffer du coke dans un gaz contenant de l"oxygene et la chloruration avec du chlore ou une combinaison chlore organique dans le courant d"hydrogene, un gaz inerte ou un gaz inerte melange a de l"oxygene et un milieu humide. Le catalyseur est de plus traite avec de l"ammoniac ou un compose contenant de l"azote, capable, dans les conditions du traitement, de desintegrer et de creer de l"ammoniac en presence d"au moins un des composants choisis dans le groupe suivant: eau, hydrogene, melange azote-oxygene. Le traitement peut etre effectue en phase liquide et en phase gazeuse a une temperature de 20 a 650 C et sous une pression de 1 a 50 atm.
