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.
Claims12
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.
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 (d50) 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.
