Abstract
The present invention relates to a catalyst for a hydrogenation reaction and a method for producing the same, and more specifically, to a catalyst for a hydrogenation reaction, wherein the catalyst includes nickel oxide as an active ingredient and copper oxide and sulfur oxide as a promoter, and especially, can control a reduction degree value according to whether or not a passivation layer of a nickel metal is removed.
Claims9
A method for producing a catalyst for a hydrogenation reaction, the method comprising the steps of:
- (a) preparing a first solution by dissolving 0.05-10 parts by weight of copper oxide and 10-50 parts by weight of a silica carrier in a solvent, based on 40-90 parts by weight of nickel oxide;
- (b) adding the first solution to a precipitation container and heating the first solution to a temperature of 60-100° C. while stirring;
- (c) preparing a second solution by mixing a pH control agent and 3-15 parts by weight of sulfur oxide, and adding the second solution dropwise to the heated first solution to prepare a precipitate;
- (d) washing and filtering the precipitate and drying the precipitate at a temperature of 100-200° C. for 5-24 hours to prepare a dried product;
- (e) calcining the prepared dried product in an air atmosphere;
- and
- (f) reducing the dried product in a hydrogen atmosphere at a temperature of 200-500° C. to prepare a reduced product.
