- W565228300 abstract "Today, many researchers have an interest in the development and introduction of new types of carbon-based materials. Dispersion metal-carbon materials got by thermo-catalytic decomposition of carbon monoxide, occupy a special place among the carbon materials. Contaminated materials with the catalyst particles, the amorphous carbon and graphitized carbon particles are received by methods of metal-carbon.The main aim of the research is to develop the technological scheme for production purified metal-carbon materials (MCM) by carbon monoxide thermo-catalytic decomposition.First, Fe2O3 particles were reduced to iron at the temperature of 1173 K. Amorphous carbon became reducer. It was established that a reduced metal from Fe2O3 was 18.7%. The experimental process of iron pentacarbonyl formation was performed at a temperature of 463 K and with a pressure of 16 MPa. Total Fe(CO)5 was 36 % by weight metal-carbon materials. Iron pentacarbonyl recovered from metal-carbon materials by temperature-vacuum processing.The oxidation of the amorphous carbon was carried out at a temperature of 843 K and the CO2 concentration of 62×10-4 kg /m3. The purified metal-carbon materials were used as filler of polyurethane marks Eracast RT - 70A on the base of isocyanate and polyol.It was established that metal-carbon materials content within 2 % increases the ultimate tensile strength almost twice and reduces limit narrowing of 14 %.Proposed and tested scheme allows you to receive MCM physicochemical methods with enough good cleaning MCM of catalyst particles and amorphous carbon." @default.
