Abstract: PROBLEM TO BE SOLVED: To provide an industrially practicable method for producing an amine by hydrogenation, consuming a small amount of a catalyst, greatly avoiding the occurrence of secondary reaction, capable of setting an excellent catalyst balance, excellently separating an inactive catalytic component. SOLUTION: This method comprises producing an amine by hydrogenating a compound containing at least one nitro group in the presence of a supported catalyst containing at least nickel as a catalytic active metal. The reduced and stabilized supported catalyst contains nickel microcrystal showing a two mode nickel microcrystal particle size distribution having maximum values at 30-80 Angstrom (300-800 nm) and 81-150 Angstrom (810-1,500 nm). The catalyst having 60-80 mass % nickel content, 0-20 mass % SiO2 content, 0-40 mass % ZrO2 content and 0-4 mass % HfO2 content in a reduced passivation state and at least 70% degree of reduction after further reduction for 1 hour at 100 deg.C is used.

Abstract: Production of amines (I) by hydrogenating at least one nitro compound (II) in presence of a supported catalyst (A) that contains nickel as catalytically active metal, optionally together with at least one metal of subgroups I, V, VI and/or VIII. The reduced and stabilized catalyst contains nickel crystallites with a bimodal distribution of size, with maxima at 30-80 and 81-150 Angstrom , and after reduction at 100 degrees C has a degree of reduction at least 70%. The support is one or more of zirconia, hafnia and/or silica and the reduced and passivated catalyst contains, by weight, 60-80% nickel; 0-20% silica; 0-40% zirconia and 0-4% hafnia.
