Abstract:
New catalysts designed as glass crystal microspheres were obtained as a result of coal and lignite combustion, hydrodynamic classification of fly ash followed by magnetic separation. The physicochemical and catalytic properties of three different systems of new catalysts were studied by SEM, XRD and Mossbauer spectroscopy. The active component of the new systems was shown to include α-Fe2O3 and a solid solution formed from magnetite and Mg(Mn)-ferrite. High-temperature eutectics (1473–1673 K) on the base of calcium aluminosilicates are represented as a matrix material. The growth of the Fe2+ concentration in the spinel phase results in increase of selectivity of C2-product formation in oxidative coupling of methane at 1123 K and in a decrease of catalytic activity of deep oxidation at 793 K.
