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.
