Реферат: It is shown that treatment of Sibunit at 2200 °С leads to a full restructuring of the structural and textural parameters of the carbon support. The structure of Sibunit becomes more ordered – according to the XRD, the interplanar distance d002 decreases by 0.005 nm compared to the original Sibunit; according to the Raman spectroscopy, ID/IG decreases from 1.59 to 1.18 and the 2D-line increases significantly. The specific surface area of Sibunit after heat treatment decreases from 303 to 29 m2/g, the total pore volume decreases by 2 times, and the pore diameter increases by 4 times. The dependence of the specific activity on the amount of the active component is extreme, and the maximum for the 1%Ru-3.4%Cs/Sib2200 catalyst and is 1.52 mol NH3/gRu*h.
