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.

First claim

The invention claimed is:

1. A catalyst for a hydrogenation reaction, comprising: 0.05-10 parts by weight of at least one first promoter selected from copper and copper oxide, 3-15 parts by weight of at least one second promoter selected from sulfur and sulfur oxide, and 10-50 parts by weight of a silica carrier as a support, based on 40-90 parts by weight of at least one active ingredient selected from nickel and nickel oxide,
wherein a reduction degree of the at least one active ingredient is controllable according to a removal of a passivation layer,
wherein the reduction degree of the at least one active ingredient is 90% or more when the passivation layer is removed, and is 45% or more when the passivation layer is not removed.

2. The catalyst for a hydrogenation reaction of claim 1 , wherein the reduction degree of the at least one active ingredient is measured by hydrogen-temperature program reduction (H 2 -TPR).

3. The catalyst for a hydrogenation reaction of claim 1 , wherein the at least one active ingredient has an average crystallite size of 3-10 nm.

4. The catalyst of claim 1 , wherein the catalyst has an average particle size (d 50 ) of 3-10 μm, and a proportion of catalyst particles having a particle size of 1 μm or less in a particle size distribution is 0.1-10% by volume.

5. The catalyst for a hydrogenation reaction of claim 1 , wherein the catalyst has a specific surface area of 150-300 m 2 /g.

6. The catalyst for a hydrogenation reaction of claim 1 , wherein the silica carrier has a specific surface area of 200-400 m 2 /g and a pore size of 3-10 nm.

7. The catalyst for a hydrogenation reaction of claim 1 , wherein the nickel forms a precipitate with the copper and the sulfur, is supported on the silica carrier, and is deposited and precipitated.

8. The catalyst for a hydrogenation reaction of claim 1 , wherein a reactant in the hydrogenation reaction is a hydrocarbon resin.

9. The catalyst for a hydrogenation reaction of claim 8 , wherein the hydrocarbon resin is at least one selected from a group consisting of a hydrocarbon resin including dicyclopentadiene (DCPD), a hydrocarbon resin including C5 fraction, and a hydrocarbon resin including C9 fraction.

10. The catalyst for a hydrogenation reaction of claim 8 , wherein the hydrocarbon resin has an APHA value of 30 or less after the hydrogenation reaction.

11. The catalyst for a hydrogenation reaction of claim 8 , wherein the hydrocarbon resin has an aromatic/olefin hydrogenation ratio of 0.1-1.0 after the hydrogenation reaction.

12. A catalyst for a hydrogenation reaction, comprising:
0.05-10 parts by weight of at least one first promoter selected from copper and copper oxide, 3-15 parts by weight of at least one second promoter selected from sulfur and sulfur oxide, and 10-50 parts by weight of a silica carrier as a support, based on 40-90 parts by weight of at least one active ingredient selected from nickel and nickel oxide,
wherein a reduction degree of the at least one active ingredient is controllable according to a removal of a passivation layer,
wherein the catalyst has an average particle size (d 50 ) of 3-10 μm, and a proportion of catalyst particles having a particle size of 1 μm or less in a particle size distribution is 0.1-10% by volume.
