INVESTIGATION OF THE CONDITIONS OF CERAMIC AND MECHANOCHEMICAL SYNTHESIS OF COMPOSITES CuO/ZnO/?-Al2O3

In this work, using the methods of X-ray phase, X-ray diffraction, synchronous thermal analysis, scanning electron microscopy, low-temperature adsorption-desorption of nitrogen, the process of obtaining CuO/ZnO/?-Al2O3 composites, which can be used as the main component of catalysts for large-tonnage processes for methanol production and monoxide conversion, was studied. carbon. The influence of the method of preparation, the nature and intensity of processing on the phase composition of the resulting precursors and the physicochemical properties of the resulting composites was established. The processes occurring at the stage of mechanochemical activation of a mixture of anhydrous CuO/ZnO/?-Al2O3 oxides, a mixture of oxides with ammonium carbonate and ethanedienic acid have been studied. The optimal parameters for obtaining CuO/ZnO/?-Al2O3 composites with a developed specific surface area and porous structure have been determined.
