PURPOSE:To provide pour point depressing activity and to improve the durability by depositing nickel, molybdenum, etc. on a carrier consisting of a mixture of iron-contg. zeolite and gamma-alumina to form the titled heavy oil reforming catalyst. CONSTITUTION:A catalyst carrier is formed of a mixture of iron-contg. zeolite consisting of crystalline metallosilicate obtained by substituting a part of Si at the apex of the crystal lattice for Fe and gamma-alumina. In this case, 20-70wt% iron-contg. zeolite is mixed with 30-80wt% gamma-alumina. When the content of the iron-contg. zeolite becomes <=20wt%, the pour point depressing activity is eliminated, and the denitrifying and desulfurizing activity is deteriorated, when the content becomes >=70wt%. A catalyst component consisting of 3-10wt% NiO, 3-10wt% CoO, 10-30wt% MoO3, and 10-30wt% WO3 is deposited on the carrier to obtain the heavy oil reforming catalyst.
