PURPOSE: To provide a rare-earth metal-containing nickel catalyst which is used as an auxiliary catalyst in hydrogenation reaction, particularly in hydrogenation of non-saturated organic compounds, for example beef tallow, lard, fish oil, vegetable oil and the like and to provide a method for manufacturing it. CONSTITUTION: A rare-earth metal-containing nickel catalyst for hydrogenation is obtained by incorporating a rare-earth metal as an auxiliary catalyst or an addition agent so that an atom ratio of total rare-earth metal per a nickel atom is 0.001-20. |
