For development of effective, stable and inexpensive catalysts of gas purification will be used the natural sorbents of East Kazakhstan. The primary purpose of research is reduced to the search and production suitable for long-term exploitation and relatively inexpensive catalysts for cleaning of gases with high activity and selectivity that have sufficient mechanical strength, thermal stability, well-developed geometric surface, stability to influence of aggressive environment and low flow resistance. The innovative technology explains the choice of natural materials of Kazakh deposits for the synthesis of carriers of catalysts for cleaning gases from toxic components, such as oxides of nitrogen and carbon.

Results of the development of multicomponent oxide catalysts based on Ni, Cu, and Cr supported on 2 % Ce/?-Al2O3 by varying the concentration of the active phase of catalyst are presented in paper. It was found that the highest degree of toluene conversion (up to 98.8 %) is observed on the three- component Ni-Cu-Cr/2% Ce/?-Al2O3 catalyst with optimal metal ratio Ni : Cu : Cr = 1.0 : 3.0 : 0.1 at GHSV = 5×103 h-1 and a temperature of 723 - 773 K. The presence of CeO2 crystals, X-ray amorphous clusters (d = 20 – 100 Å) of variable valence metal oxides NiO and CuO as well as solid metal solutions CuO (NiO) was detected on the surface of optimum catalyst calcined at 873 K using XRD and electron microscopy methods.
