A method for preparing hexadecahydropyrene, comprising: carrying out the hydrogenation reaction to hydrocarbon oil containing pyrene compounds in the presence of a hydrogenation catalyst, wherein the pyrene compounds are selected from at least one of pyrene and unsaturated hydrogenation products thereof, the hydrogenation catalyst contains a carrier and an active metal component loaded on the carrier, the active metal component is Pt and/or Pd, the carrier contains a small crystal size Y zeolite, alumina and amorphous silica-alumina, the small crystal size Y zeolite has an average grain diameter of 200-700nm, a molar ratio of SiOto AlOof 40-120, a relative crystallinity of ≥95%, a specific surface area of 900-1,200m/g, the pore volume of secondary pores in 1.7-10nm diameter is more than 50% of the total pore volume. According to the method for preparing hexadecahydropyrene in the present invention, a high-purity hexadecahydropyrene product can be prepared with high yield. |
