The possibility of amines synthesis from a mixture of carbon dioxide, hydrogen, and ammonia in a slurry reactor in the presence of bifunctional catalytic suspensions 1% Fe–1% Co–0.5% Al2O3–0.02% BaO was studied. In the presence of the suggested catalysts, primary amines with up to 16 carbon atoms in the chain are formed with 52–60% feed conversion in the yield reaching 2.4 g per 1 m3 of the initial syngas. The effect of the catalyst activation conditions on its activity in the tandem synthesis of higher amines and on the chain length in the aliphatic amines formed was determined: the increasing of pretreatment time with hydrogen from 2 to 4 h, the maximum feed conversion shifts toward lower temperatures by 40°C with a simultaneous significant increase of С13–С16 monoalkylamines content in the reaction products.
