Title (EN) METHOD FOR REGENERATING CATALYST FOR BUTADIENE PRODUCTION
(FR) PROCÉDÉ POUR RÉGÉNÉRER UN CATALYSEUR DESTINÉ À LA PRODUCTION DE BUTADIÈNE
(JA) ブタジエン製造用触媒の再生方法
Abstract:
(EN) The purpose of the present invention is to provide a method for regenerating a catalyst for butadiene production by removing coke-like substances which have adhered to the catalyst for butadiene production and to the inside of a reactor as a result of the oxidative dehydrogenation of n-butene performed in the presence of the catalyst. The present invention is a catalyst regeneration method in which coke-like substances that have adhered to the inside of a reactor are removed, the reactor having been used in the oxidative dehydrogenation of a butene compound and being packed with a catalyst for butadiene production that had a given composition before the use. The method comprises a treatment step in which the reactor is treated with a first gas containing oxygen in an amount larger than 0 vol% but not larger than 21 vol% and a supply step in which a second gas containing water vapor in an amount larger than 0 vol% but not larger than 42 vol% and containing oxygen in an amount larger than 0 vol% but not larger than 21 vol% is subsequently supplied to the reactor. In the method, the temperature of a heat carrier circulating through the reactor is regulated to 200ºC or higher but lower than 400ºC, and the temperature of the heat carrier is made constant during the period from completion of the treatment step to completion of the subsequent supply step. The first and second gases differ in water vapor content.
(FR) L'objectif de la présente invention est de fournir un procédé pour régénérer un catalyseur destiné à la production de butadiène par élimination des substances de type coke qui ont adhéré au catalyseur destiné à la production de butadiène et à l'intérieur d'un réacteur en conséquence de la déshydrogénation oxydative de n-butène exécutée en présence du catalyseur. La présente invention est un procédé de régénération de catalyseur dans lequel des substances de type coke qui ont adhéré à l'intérieur d'un réacteur sont éliminées, le réacteur ayant été utilisé dans la déshydrogénation oxydative d'un composé de butène et étant garni d'un catalyseur destiné à la production de butadiène qui avait une composition donnée avant l'utilisation. Le procédé comprend une étape de traitement dans laquelle le réacteur est traité avec un premier gaz contenant de l'oxygène en une quantité supérieure à 0 % en volume, mais pas supérieure à 21 % en volume et une étape d'alimentation dans laquelle un second gaz contenant de la vapeur d'eau en une quantité supérieure à 0 % en volume, mais pas supérieure à 42 % en volume et contenant de l'oxygène en une quantité supérieure à 0 % en volume, mais pas supérieure à 21 % en volume est par la suite alimenté au réacteur. Dans le procédé, la température d'un caloporteur circulant à travers le réacteur est régulée à 200 °C ou plus, mais moins de 400 °C, et la température du caloporteur est rendue constante pendant la période allant de l'achèvement de l'étape de traitement à l'achèvement de l'étape d'alimentation ultérieure. Les premier et second gaz diffèrent en teneur en vapeur d'eau.
(JA) 本発明は、n-ブテンをブタジエン製造用触媒の存在下に酸化的脱水素反応させることで触媒並びに反応器内に付着したコーク状物質を除去するブタジエン製造用触媒の再生方法を提供することを目的とする。本発明は、ブテン類の酸化的脱水素反応に使用された、使用前の組成が所定の組成であるブタジエン製造用触媒が充填された反応器内のコーク状物質を除去する触媒の再生方法であって、0容量%より大きく21容量%以下の酸素を含む第1のガスで反応器を処理する処理工程と、次いで0容量%より大きく42容量%以下の水蒸気、及び0容量%より大きく21容量%以下の酸素を含有する第2のガスを反応器に供給する供給工程とを含み、反応器内を循環する熱媒の温度を200℃以上400℃未満の範囲とし、処理工程の終了時点からそれに続く前記供給工程の終了時点までの間、熱媒の温度を一定にし、第1及び第2のガスにおける水蒸気の含有量が異なる方法である。
