Abstract: The present invention discloses a catalytic hydrogenation method for carbon nine resin, comprising the following steps: 1) adding a Pt—W—Y/γ-Al2O3 catalyst in the first half of a fixed bed, adding a Pd—Zr—Nd/γ-Al2O3 catalyst in the second half of the fixed bed, and feeding hydrogen for reduction; and 2) catalytic hydrogenating the pretreated carbon nine resin in the fixed bed. In the present invention, different catalysts capable of reacting under the same catalytic conditions are added in the first and second halves of the fixed bed, and the two different catalysts play different roles, and can be active and complementary to each other under the same conditions. The synergistic effect of the two catalysts plays a good catalytic role. Moreover, the production process is simplified, and the production cost is saved.
