Abstract
The possibility of producing carbon–carbon composites by catalytic chemical vapor deposition has been investigated. Anthracite dust of deposits in the Gorlovskii basin was used as an initial carbon matrix. Salts of nickel acetate and iron oxalate were used to form catalytically active metal particles (nickel and iron) on the surface of anthracite. The precursor salts were supported by an incipient wetness impregnation of anthracite samples with aqueous solutions. Optimal conditions of thermal treatment in inert and reducing media were determined for the used salts. Scanning electron microscopy was used to study the secondary structures of the original anthracite with supported metals and synthesized carbon–carbon composites. Using the low-temperature nitrogen adsorption method, a significant increase in the specific surface area of an anthracite sample with supported nickel as a result of its treatment in an atmosphere of saturated C2–C4 hydrocarbons at 600°C was demonstrated.
期刊介绍：
The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
