The present invention relates to a method for preparing an improved supported catalyst for hydrocracking of petroleum residue. The method of preparing supported catalyst is considered for possessing textural and mechanical properties for hydrocracking of petroleum residue. The improved supported catalyst comprises formulated alumina support extrudates and at least one metal from Group VIB and VIIIB of the periodic table. The supported catalysts are 0 characterized by definite combination of pseudo-boehmite and mixture of acids followed by metal component molar ratios. The final catalyst with homogeneously dispersed active metals is effective in converting petroleum residue for producing distillates.
