The application discloses a method for cracking tar into high value-added products, which adopts a route of separating light components by fractional distillation and then hydrogenating heavy components, so that the yield of target products can be affected by hydrogenation of naphthalene, methyl naphthalene and the like below 250 DEG C in the process of hydrocracking, and on the other hand, the components below 250 DEG C account for about 30% to 50%, so that the hydrogen consumption in the subsequent hydrocracking can be reduced by separating the components in advance. After the heavy fraction is subjected to hydrocracking, part of polycyclic aromatic hydrocarbons in the heavy fraction can be cracked into part of monocyclic aromatic hydrocarbons, which can be used for producing aromatic solvent oil, so that the light fraction in the hydrocracking product is separated and mixed into the light fraction generated by pre-fractionation, and the next step processing is carried out, so that the yield of high value-added products can be further improved.
