Abstract

Technical characteristics and activity of oxide catalyst, applied on fibers ALSIFLEX-KT1600, were studied. As a catalytic contact, we used spinel (% by weight): Al2O3 – 10; MgO – 3; (Cr2O3+NiO) – 0.4.

As a result of conducted studies, the structure of the carrier and the catalyst were studied, anisotropy of properties was established, and technical characteristics were deftermined: density of the catalyst, which made up 0.3 g/m3, 90.4 % porosity, hydrodynamic resistance of the catalyst’s layer at different voluminous loads, and specific surface area. Catalyst activity was studied at complete methane oxidation. Activation energy Ea made up 86.241 kJ/mol, while temperature of complete methane conversion amounted to 800 °C and that of 50 % conversion made up 550 °C. Macrokinetic equation of the rate of complete methane oxidation for this catalyst was obtained. Research results proved high activity of the catalyst, resistant to exposure to high temperatures (1000–1200 °C) and volumetric loading (t=0.03–0.05 s).

The obtained results indicate relevance of the use of the developed catalyst for catalytically stabilized combustion of hydrocarbon fuels with improved performance, technological and environmental characteristics.
