The present invention relates to a nickel catalyst for a hydrogenation reaction and a manufacturing method therefor, and relates to a nickel catalyst added in a hydrogenation reaction for improving a color of a hydrocarbon resin. The catalyst according to the present invention has a small crystallite size and improves dispersibility, while having high nickel content, and thus can provide high activity in hydrogenation reactions.

Nickel catalyst for hydrogenation reaction and manufacturing method therefor

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.

Catalyst for hydrogenation reaction and preparation method for same

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.

Catalyst for hydrogenation and method for preparing same

Provided are a hydrogenation reaction catalyst and a preparation method therefor, and more particularly, to a hydrogenation reaction catalyst including sulfur as a promoter, thereby selectively hydrogenating 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 an aromatic group, and a preparation method therefor.

Hydrogenation reaction catalyst and preparation method therefor

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.

The present disclosure relates to a method for measuring aromatic contents in a hydrocarbon solution. More specifically, it relates to a measurement method capable of quickly and accurately checking aromatic contents in a compound, particularly in a hydrocarbon, in a solution state without a high-temperature drying process.
