A method for preparing hexadecahydropyrene includes the step of carrying out the hydrogenation reaction to hydrocarbon oil containing pyrene compounds in the presence of a hydrogenation catalyst. 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 and 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 200-700 nm, a molar ratio of SiO.sub.2 to Al.sub.2O.sub.3 of 40-120, a relative crystallinity of ≥95%, and a specific surface area of 900-1,200 m.sup.2/g.
