Zusammenfassung:The present invention relates to a molecular size-selective hydrocracking catalyst for preparing a light aromatic hydrocarbon in the range of C_6-C_9 with an increased BTX content from a polycyclic aromatic hydrocarbon, a method for preparing the same, and a method for preparing a light aromatic hydrocarbon in the range of C_6-C_9 with an increased BTX content using the same. More particularly, by using a catalyst supported only on Mo, which is a VIB group metal, or on Mo, which is a VIB group metal, and Co, which is a VIIIB group metal, together with regard to a composite zeolite carrier of zeolite beta, zeolite Y containing mesopores, and zeolite ZSM-5, it is possible to achieve the effect of obtaining light aromatic hydrocarbons in the range of C_6-C_9 with an increased BTX content from the oils of oil refineries and petrochemical processes having a high content of polycyclic aromatic hydrocarbons such as bicyclic aromatics, etc., at a high yield. 본 발명은 다환 방향족 탄화수소로부터 BTX 함량이 증가된 C-C범위의 경방향족 탄화수소 제조용 분자크기 선택성 수소화 분해 반응용 촉매, 이의 제조방법 및 이를 이용한 BTX 함량이 증가된 C-C범위의 경방향족 탄화수소의 제조방법에 관한 것으로, 보다 상세하게는 제올라이트 베타, 메조기공을 포함하는 제올라이트 Y 및 제올라이트 ZSM-5의 복합 제올라이트 담체에 ⅥB족 금속인 Mo 단독 또는 ⅥB족 금속인 Mo과 ⅧB족 금속인 Co가 함께 담지된 촉매를 사용함으로써, 2환 방향족 등과 같은 다환 방향족 탄화수소 함량이 높은 정유 및 석유화학 공정의 유분으로부터 BTX 함량이 증가된 C-C범위의 경방향족 탄화수소를 높은 수율로 얻는 효과를 달성할 수 있다.
