1. A hydrogenation reaction catalyst for petroleum resin; comprising nickel, a promoter, and a carrier,
wherein the promoter comprises copper and sulfur,
the carrier is at least one selected from the group consisting of silica and alumina,
the nickel has an average crystal size of 1 nm to 10 nm and the hydrogenation reaction catalyst has an average particle size of 1 μm to 20 μm,
a content of the nickel is in a range of 62 parts by weight to 65 parts by weight based on 100 parts by weight of the hydrogenation reaction catalyst,
a content of the copper is in a range of 0.8 parts by weight to 1 parts by weight based on 100 parts by weight of the hydrogenation reaction catalyst,
a mole ratio of the sulfur to the nickel is in a range of 0.02:1 to 0.2:1,
a content of the sulfur is in a range of 2.2 parts by weight to 2.9 parts by weight based on 100 parts by weight of the hydrogenation reaction catalyst,
the catalyst is to selectively hydrogenate an olefin by changing a relative hydrogenation rate of the olefin and an aromatic group during a hydrogenation reaction of an unsaturated hydrocarbon compound containing the aromatic group of the petroleum resin, and
the aromatic/olefin hydrogenation ratio is 0.3-0.8.
