Title: Filamentous carbon catalytic deposition of coal-tar pitch fraction on corundum

Abstract

Our work was focused on deposition of volatile hydrocarbons of carbonaceous precursor on corundum wafer, taking advantage of a metallic catalyst incorporated in precursor. Coal tar-pitch, namely a fraction soluble in toluene, served as precursor material for deposition of filamentous material. The toluene-soluble fraction of tar-pitch originally contained metallic particles of iron and nickel. During heat treatment up to 1000{sup o}C, metallic particles accompanied the volatile hydrocarbons conducive to forming a filamentous deposit. The deposit obtained demonstrates a semicrystalline material that has an irregular filamentous structure with an average filament diameter of 30 {mu}m. The presence of catalysts after the deposition process was proved in the deposit but catalysts were not found in the residuum.

  • In order to improve the life of the lining of various thermal units, periclase-carbon refractories (including those obtained by impregnating the fired products with carbonaceous substances) are being widely used in recent years. This paper presents the results of their studies on the effect of the nature of the carbonaceous substance, heat treatment of the products, and the temperature and the duration of testing on the degree of burning-up (depletion) of the carbonaceous constituent in the periclase products. They studied fired periclase products (measuring 750 x 225 x 225 mm) that were impregnated with coal tar (prepared using pitch andmore » anthracene oil) or a medium-temperature pitch (GOST 1038-75) and the products impregnated with pitch after heat treatment.« less
  • In this paper the kinetics of the hydrogenation reaction of the main aromatic hydrocarbons found in a light fraction of an anthracene oil are studied employing two different commercial catalysts: reduced nickel and sulfided nickel-molybdenum. Kinetic expression considering the effect of temperature and hydrogen pressure are obtained. The effect of sulfur concentration in the feed is also evaluated. Specific reaction rates and activation energies are calculated assuming first order with respect to all reagents including hydrogen in hydrogenation reactions. The concentrations of naphthalene, acenaphthene, phenanthrene, fluoranthene, and pyrene are fitted to a first-order decay. The reaction path for anthracene involvesmore » a reversible reaction between 9,10-dihydroanthracene and 1,2,3,4-tetrahydro-anthracene.« less
  • The effect of the content of ..cap alpha../sub 1/ pitch fraction on such properties as the density, compression strength, and specific electrical resistance of electrodes and anode compositions of pitch coke and graphite is considered. The subject of the investigation was a medium temperature coal pitch. The heat treatment of the initial pitch was conducted at 300/sup 0/C in an inert medium with a constant temperature maintenance of 1 to 6 hours. (JMT)
