Zusammenfassung:	The present invention relates to a catalyst for synthesis of hydrogen peroxide by means of the anthraquinone process and for recovering a working solution, and to a method of preparing the catalyst. Disclosed is a catalyst in which palladium, magnesium, and cerium components are uniformly distributed in alumina, or a palladium component is distributed in alumina spheres in a ring shape while magnesium and cerium components are uniformly distributed in alumina. In addition, a method of preparing the catalyst is disclosed. La présente invention concerne un catalyseur pour la synthèse de peroxyde d'hydrogène au moyen du procédé à l'anthraquinone et pour la récupération d'une solution de travail, et un procédé de préparation du catalyseur. L'invention concerne un catalyseur dans lequel des composants palladium, magnésium et cérium sont uniformément répartis dans de l'alumine, ou un composant palladium est distribué dans des sphères d'alumine en forme d'anneau tandis que les composants magnésium et cérium sont uniformément répartis dans de l'alumine. La présente invention concerne en outre un procédé de préparation du catalyseur. 본 발명은 안트라퀴논 방법에 의한 과산화수소의 제조 및 작동용액을 재생하는 촉매 및 이의 제조방법에 관한 것으로, 팔라듐, 마그네슘 및 세륨 성분이 알루미나에 균일하게 분포되거나, 팔라듐 성분이 알루미나 구체에 고리 형태로 분포되고 마그네슘 및 세륨 성분이 알루미나에 균일하게 분포되는 촉매 및 이의 제조방법이 개시된다.
