ELECTRO-EXPLOSIVE IRON-BASED POWDERS AS CATALYSTS OF HYDROCARBONS SYNTHESIS FROM CO AND H2
Using the complex of methods, which includes laser diffraction, transmission electron microscopy, X-ray phase analysis, specific surface area and pore size determination, dispersive content and morphology of electro-explosive iron-based powder particles were studied. Catalytic activity of ultra-dispersive iron-based powders in Fisher-Tropsch hydrocarbons synthesis from CO and H2 was estimated by paramagnetic particles concentration obtained during electron paramagnetic resonance. Syntheses at different compositions of feed gas were carried out on laboratory-scale plant. Parameters of catalyst phases before and after synthesis were determined. In a wire electrical explosion iron powders can be prepared with the specified properties (phase composition, particle size and structure). Powder Fe (CO) can be used as the FT synthesis catalyst without recovery, as in the PCI in carbon monoxide atmosphere formed phase composition required to activate hydrocarbon synthesis reaction of a mixture of CO and H2.
