Zusammenfassung:The present invention relates to: a hydrocracking catalyst for preparing a C6-C9 light aromatic hydrocarbon, having an increased BTX content, from a polycyclic aromatic hydrocarbon; a method for preparing the same; and a method for preparing a C6-C9 light aromatic hydrocarbon, having an increased BTX content, by using the same and, more specifically, an effect of obtaining, in a high yield, a C6-C9 light aromatic hydrocarbon, having an increased BTX content, from the by-products, containing polycyclic aromatic hydrocarbons such as naphthalene and alkyl-naphthalene, of petroleum refining and petrochemical processes can be achieved by using a catalyst in which one or more metals selected from group VIII and one or more metals selected from group VIB are supported on a composite zeolite support of zeolite beta and zeolite ZSM-5. La présente invention concerne : un catalyseur d'hydrocraquage pour préparer un hydrocarbure aromatique léger C6-C9, ayant une teneur en BTX augmentée, à partir d'un hydrocarbure aromatique polycyclique; un procédé de préparation de celui-ci; et un procédé de préparation d'un hydrocarbure aromatique léger en C6-C9, ayant un contenu en BTX augmenté, obtenu à l'aide de ce catalyseur. Plus spécifiquement, l'obtention, avec un rendement élevé, d'un hydrocarbure aromatique léger en C6-C9, ayant une teneur en BTX augmentée, à partir de sous-produits, contenant des hydrocarbures aromatiques polycycliques tels que le naphtalène et l'alkyl-naphtalène, de raffinage de pétrole et de processus pétrochimiques peut être obtenu en utilisant un catalyseur dans lequel un ou plusieurs métaux choisis dans le groupe VIII et un ou plusieurs métaux sélectionnés dans le groupe VIB sont supportés sur un support de zéolite composite de zéolite bêta et de zéolite ZSM-5. 본 발명은 다환 방향족 탄화수소로부터 BTX 함량이 증가된 C6-C9 범위의 경방향족 탄화수소를 제조하는 수소화 분해 반응용 촉매, 이의 제조방법 및 이를 이용한 BTX 함량이 증가된 C6-C9 범위의 경방향족 탄화수소의 제조방법에 관한 것으로, 보다 상세하게는 제올라이트 베타 및 제올라이트 ZSM-5의 복합 제올라이트 담체에 VIII족에서 선택되는 하나 이상의 금속, 및 VIB족에서 선택되는 하나 이상의 금속이 담지된 촉매를 사용함으로써, 나프탈렌, 알킬-나프탈렌 등과 같은 다환 방향족 탄화수소가 포함되어 있는 정유 및 석유화학 공정의 부산물로부터 BTX 함량이 증가된 C6-C9 범위의 경방향족 탄화수소를 높은 수율로 얻는 효과를 달성할 수 있다.
