Method for preparing hydrocracking catalyst

The present invention provides a process for preparing a supported catalyst, preferably a hydrocracking catalyst, comprising at least the steps of: a) providing a zeolite Y having a bulk silica to alumina molar ratio (SAR) of at least 10; b) contacting the zeolite Y provided in step a) with a base and a surfactant, thereby obtaining a zeolite Y having an increased mesoporosity; c) shaping the zeolite Y having an increased mesoporosity obtained in step b), thereby obtaining a shaped 10 catalyst support; d) calcining the shaped catalyst support obtained in step c) in the presence of the surfactant of step b), thereby obtaining a calcined catalyst support; e) impregnating the catalyst support calcined in step d) with a noble metal component, thereby obtaining the supported catalyst. 本发明提供了一种制备负载型催化剂、优选地加氢裂化催化剂的方法，该方法至少包括以下步骤：a)提供本体二氧化硅与氧化铝摩尔比(SAR)为至少10的沸石Y；b)使步骤a)中提供的沸石Y与碱和表面活性剂接触，从而获得具有增加的介孔率的沸石Y；c)使在步骤b)中获得的具有增加的介孔率的沸石Y成型，从而获得成型的10催化剂载体；d)在步骤b)的表面活性剂的存在下煅烧步骤c)中获得的成型的催化剂载体，从而获得经煅烧的催化剂载体；e)用贵金属组分浸渍步骤d)中煅烧的催化剂载体，
