CATALYST FOR HYDROGENATION REACTION AND PREPARATION METHOD FOR SAME

WIPO Patent Application WO/2020/141705

A1

The present invention relates to a catalyst for a hydrogenation reaction of petroleum resin, and a preparation method for same, wherein the catalyst is a nickel powder catalyst comprising nickel (Ni), copper (Cu), and sulfur (S), and more specifically, a nickel-based catalyst for a hydrogenation reaction to be added to a hydrogenation reaction in order to improve the color of petroleum resin. According to one example of the present invention, provided is a catalyst for a hydrogenation reaction comprising, with respect to 100 parts by weight of a total dry weight including a support: 40-80 parts by weight of nickel; 0.01-5 parts by weight of copper; 1-10 parts by weight of sulfur; and 10-60 parts by weight of a silica support. Thus, the catalyst can improve the quality of petroleum resin. Furthermore, the catalyst can provide colorless, odorless, and transparent water-white petroleum resin with improved thermal stability by eliminating unsaturated bonds in the petroleum resin.
