Abstract: Nitro-compounds are hydrogenated with an activated Ni catalyst whose Ni/Al alloy also contained one or more elements from the list of Cu, Ag and Au prior to activation. In combination with the Group IB elements mentioned above, this catalyst can also be doped with other elements via their addition to the Ni/Al alloy prior to activation and/or they can be adsorbed onto the surface of the catalyst either during or after the activation of the alloy. The suitable doping elements for the alloy prior to activation in combination with the group IB elements mentioned above are one or more of the elements from the list of Mg, Ti, Ce, Cr, V, Mo, W, Mn, Re, Fe, Co, Tr, Ru, Rh, Pd, Pt and Bi. The suitable doping elements that may be adsorbed onto the surface of the catalyst that was previously doped in the alloy prior to activation with the group IB elements mentioned above are one or more elements from the list Mg, Ca, Ba, Ti, Ce, V, Cr, Mo, W, Mn, Re, Fe, Ru, Co, Rh, Ir, Pd, Pt, Ni, Cu, Ag, Au and Bi.

Abstract: Nitro-compounds are hydrogenated with an activated Ni catalyst that is doped during and/or after activation with one or more elements from the list of Mg, Ca, Ba, Ti, Zr, Ce, Nb, Cr, Mo, W, Mn, Re, Fe, Co, Ir, Ni, Cu, Ag, Au, Rh, Ru and Bi whereas the Ni/Al alloy may not, but preferentially can contain prior to activation one or more doping elements from the list of Ti, Ce, V, Cr, Mo, W, Mn, Re, Fe, Ru, Co, Rh, Ir, Pd, Pt and Bi. If the Ni/Al alloy contained one or more of the above mentioned suitable alloy doping elements prior to activation, the resulting catalyst can then be doped with one or more of the elements from the list of Mg, Ca, Ba, Ti, Zr, Ce, V, Nb, Cr, Mo, W, Mn, Re, Fe, Ru, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au and Bi by their adsorption onto the surface of the catalyst.

Abstract: Nitro-compounds are hydrogenated with an activated Ni catalyst that has an average particle size (APS) less than 25 ?m and is doped with one or more elements from the list of Mg, Ce, Ti, V, Nb, Cr, W, Mn, Re, Fe, Ru, Co, Rh, Ir, Pt, Cu, Ag, Au and Bi via its/their addition to the alloy before activation and/or doped with one or more elements from the list of Mg, Ce, Ti, V, Nb, Cr, W, Mn, Re, Fe, Ru, Co, Rh, Ir, Ni, Cu, Ag, Au and Bi by their adsorption onto the surface of the activated catalyst.

Abstract: A process for the continuous catalytic conversion of organic compounds, that, together with unwanted attendant materials, form a starting substance: first the organic compounds of the starting material are purposely extracted by means of condensed fluids. Then the extract, containing the condensed fluids and organic compounds as the reaction mixture is contacted with a catalyst for the catalytic conversion of the organic compounds to form a product mixture, which contains the individual products of the catalytic conversion. The product mixture is separated from the reaction mixture and the fluids employed are, optionally, conducted back for extraction.
