With the use of the electron microscopy and X-ray analysis the regularities of carbon sediments formationat methane and propane pyrolysis on zeolites, Kazakhstan natural clays, chrome and bauxite sludges, which contain metal oxides of iron subgroup, have been studied. The kinetic parameters of carbon forma-tion at methane decomposition on the surface of zeolite – CoO mixture were investigated by method of thermogravimetric analysis. The morphology and structure of forming carbon fibrils, with the metal par-ticles fixed at their ends, have been investigated, and the formation of carbon fibrils branched pattern, socalled octopus, has been discovered. Greek walnut shells and grape seeds carbonization, their immobiliza-tion by the cells of selective absorption of heavy metal and sulfur dioxide ions have been also studied. Theexamples of metal-carbon composites using as adsorbents for wastewater purification, C3- C4 hydrocarboncracking catalysts and refractory materials with improved properties have been considered.
