description The regeneration of working solutions is an important procedure during the anthraquinone process for hydrogen peroxide production, which commonly uses activated alumina for this purpose. This study investigated the impact of different factors on regeneration performance using a fixed bed reactor and found that temperature, contact time, and the catalyst's active component were the key factors. Catalysts with higher alkali content improve regeneration performance. The catalysts' binders and the post‐treatment method affect their physical strength, but steam counteracts this due to the reaction of the active component with water. La régénération des solutions de travail est une procédure importante durant le processus à l'anthraquinone pour la production du peroxyde d'hydrogène, dans laquelle on utilize couramment de l'alumine activée. Cette étude a permis d'examiner l'impact de différents facteurs sur le rendement de régénération en utilizant un réacteur à lit fixe et on a conclu que la température, le temps de contact et le composant actif du catalyseur étaient les facteurs clés. Les catalyseurs ayant de forts contenus en alcalis amélioraient le rendement de régénération. Les liants des catalyseurs et la méthode de post‐traitement influencent leur puissance physique mais la vapeur contrebalance cela en raison de la réaction du composant actif avec l'eau.
