Ultradispersed Hydrocarbon Synthesis Catalyst from CO and H_2 Based on Electroexplosion of Iron Powder

摘要

The structure and properties of disperse particles of electroexplosive iron-based powder are studied with a laser diffraction method, transmission electron microscopy analysis and X-ray photography. The catalytic activity of ultradispersed iron powders in the synthesis of hydrocarbons from CO and H_2 by Fischer - Tropsch method is measured by concentration of the paramagnetic particles with electron paramagnetic resonance. In the laboratory of catalytic plant, hydrocarbons are synthesized at various feed mixture. Composition of liquid and gas products of synthesis are studied. Under explosion conditions, the electric wires of iron powders can be prepared with the specified properties (phase composition, particle size and structure). Powder of Fe (CO) can be used as a catalyst of the Fischer - Tropsch synthesis without reduction since during electrical explosion in an atmosphere of carbon monoxide generated phase structure needed to activate hydrocarbon synthesis reaction of a mixture of CO and H_2.
