| Abstract/Summary |
The combustion of single coal char particle in carbon dioxide atmosphere was studied. In experiments, brown coal from coal mine Cígeľ (Slovakia) has been used. The combustion was monitored using the TGA method. The experimental equipment allowed to study the mass of the particle and temperatures inside of the particle and on its geometrical surface. Time dependences of these parameters were measured during combustion in different gas mixtures of carbon dioxide and argon (5—100 vol. % of CO2) and in the temperature range 800—1300ºC. For some samples, the properties such as pore size distribution, specific surface area, and porosity were determined by the mercury porosimetry and the nitrogen sorption method. The results showed that coal char particle combustion proceeded via a homogeneous mechanism. The microstructure properties of a partially combusted particle showed an important increase in the specific surface area compared to the original coal char particle, which was mai
