AbstractAbout AuthorsReferences
The influence of carbon and its gasification products on the process of dolomite decarbonization has been studied by the method of thermodynamic analysis. The intensifying effect of organic matter during the heat treatment of magnesium carbonate is shown. In addition to carbon, decarbonization reactions are affected by gases released as a result of gasification of the organic part of carbon enrichment waste. It is theoretically proved that the organic component of carbon enrichment waste contributes to lowering the temperature of the beginning and end of dolomite dissociation. To confirm the theoretical premises, experimental studies of the behavior of organomineral mixtures during heating were carried out. The products of thermochemical transformations of the organic component of carbon enrichment waste increase the efficiency of the dolomite decarbonization process. The organic component of the waste reduces the temperature of the dolomite decarbonization process.
