Catalyst for hydrogenation and method for preparing same

A method for preparing a catalyst for hydrogenation, comprising the steps of:

• preparing a first solution by dissolving a nickel precursor in a solvent, so that a weight concentration (g/L) of nickel in a solution is 25 to 250;
• preparing a second solution by adding a copper precursor to the first solution, so that a weight concentration (g/L) of copper in a solution is 0.01 to 5;
• preparing a third solution by adding a silica carrier to the second solution and dispersing the silica carrier, so that a weight concentration (g/L) of silica in a solution is 10 to 50;
• adding the third solution to a precipitation container and stirring and heating the third solution to a temperature to 50-120° C.;
• adding a pH control agent to the heated third solution and depositing the nickel and copper precursors on the solid silica carrier forming a precipitation;
• washing and filtering the supported catalyst and drying the supported catalyst at 100-200° C. for 5 to 24 hours;
• calcining the dried catalyst at a temperature of 200-500° C. in air;
• and
• activating the calcined catalyst by reducing the calcined catalyst to a temperature of 200-500° C. in a hydrogen atmosphere,
• wherein a particle size distribution of the catalyst has D10 of 2 μm or more, D50 of 5-7 μm, and D90 of 15 μm or less, and
• wherein the nickel is included in an amount of 50 parts by weight or more, and
• nickel oxide and copper oxide are included, wherein a ratio between a weight of the copper oxide to a weight sum of the nickel oxide and the copper oxide is 0.01-2.0:100.
