Abstract The effect of composition of the chlorine-containing precursors of ruthenium and heat treatment conditions on the preparation of catalysts supported on carbon composite Sibunit for the ammonia synthesis was studied. The activity of Ru-Ba/Sibunit samples was shown to depend on ruthenium dispersion and residual chlorine content in the catalyst. The removal of outer-sphere chloride ions from ammonia complexes of ruthenium via ionic exchange and the replacement of hydrogen reduction of the Ru precursor by calcination in an inert atmosphere prevent sintering and agglomeration of the active component particles, thus enhancing the catalyst activity.
