PURPOSE : A hydrocracking method using a zeolite catalyst containing two separate hydrogenating functional groups is provided to increase yield by specifying the whole silicon to aluminum atomic rate of dealuminated zeolite and by containing nickel elements. CONSTITUTION : A catalyst includes one or more hydrogenating-dehydrogenating elements and a support. The support is selected from a group including elements of a VIB family and a non-rare VIII family in a periodic table. A method for manufacturing the catalyst includes the following : dealuminated zeolite is prepared; 0.5 to 3 weight%% of nickel elements based on the total mass of zeolite is deposited to the dealuminated zeolite; the resultant product is mixed with a porous inorganic matrix and is shaped to obtain the support; one or more hydrogenating-dehydrogenating element is applied to the matrix; and a drying and a calcinating process are implemented.
