Реферат:
The problems of creation ruthenium-carbon catalysts for ammonia synthesis from initial compounds of ruthenium and alkali metals, accessible and convenient for use, are surveyed in order to prepare the new generation ammonia catalyst for the industrial application. Graphite-like active carbon ‘Sibunit’ was used as a support for preparation of the catalysts. Potassium and cesium as promoters were introduced through hydroxides. Ruthenium (II) and (III) complexes with N-containing polydentate organic ligands are used for direct regulation of a dispersity of ruthenium-potassium and ruthenium-cesium systems. The important role at preparation of the active catalysts is stipulated by a nature of inner sphere ligand and even outer sphere of a counter-ion in the ruthenium complexes. It has been found that samples synthesized from Cl-free Ru precursors possess a considerably high activity in the ammonia synthesis at temperatures 573÷673 K, pressure 5–50 bar, N2:H2 = 1:3, than that prepared from Cl-containing compounds. It is assumed that the most active are catalytic centres, containing ruthenium in low degrees of oxidation.
