Abstract

The carbon concentrate (C = 40% by the weight) based on shungite ore has been obtained by chemical enrichment. The concentrate is used as carbon-metal carrier of catalyst. It has been established that the best affinity of the C-Pd is due to the high content of carbon. A partial recovery of palladium due to electron-donor centers of the surface of the carbon matrix occurs on the shungite carrier as a result of chemisorption on H2PdCI4. The carbon-metal catalysts have been researched by electron microscopy and X-ray fluorescence analysis.
