Abstract: The present invention relates to a catalyst for hydrogenation and a method for preparing the same, and more specifically, provides a catalyst having improved activity by including copper and copper oxide as a promoter when a hydrogenation catalyst including nickel is prepared by using a deposition-precipitation (DP) method. Accordingly, a catalyst having high activity may be provided in a hydrogenation process of a hydrocarbon resin.

Abstract: The present invention relates to a catalyst for a hydrocarbon resin hydrogenation reaction and a preparation method for the same, wherein the catalyst is a nickel powder catalyst including nickel (Ni), copper (Cu), and sulfur (S), and more particularly, a nickel-based catalyst for a hydrogenation reaction, which is added to a hydrogenation reaction in order to improve the color of the hydrocarbon resin. According to an embodiment of the present invention, provided is a catalyst for a hydrogenation reaction, includes 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 based on 100 parts by weight of the entire dried catalyst including a support. Therefore, the catalyst can improve the quality of hydrocarbon resin. Furthermore, the catalyst can provide colorless, odorless, and transparent water-white hydrocarbon resin with improved thermal stability by removing unsaturated bonds in the hydrocarbon resin.

Abstract: According to the present invention, when preparing a hydrogenation catalyst including nickel as an active ingredient, the reduction of nickel can be facilitated by using copper and sulfur as a promoter. In particular, the present invention can provide a catalyst which, while having a high nickel content, includes sulfur oxide and nickel oxide in a particular range, and thus exhibits even higher selective reduction degree for olefins while having high activity of the catalyst.
