Claim 10:
11. A method for preparing the catalyst for the hydrogenation reaction according to claim 1, the method comprising the steps of:
(a) preparing a first solution by dissolving, in a solvent, 40-80 parts by weight of nickel, 0.01-5 parts by weight of copper, and 10-60 parts by weight of a silica support based on 100 parts by weight of the entire dried catalyst including a support;
(b) adding the first solution to a precipitation container, stirring the first solution, and heating the first solution to a temperature of 60-100° C.;
(c) after the heating, preparing a second solution by adding a pH control agent and a sulfur precursor in a precipitation container, and preparing a precipitate by adding the second solution dropwise to the first solution;
(d) washing and filtering the precipitate and drying the precipitate to prepare a dried product and
(e) reducing the dried product in a hydrogen atmosphere to prepare a reduced product.
