Description
Summary:The three coal char samples gasification processes at various temperature in carbon dioxide were studied via thermogravimetry analyzer Netzsch STA 449. Samples of Kuznetskiy deposit anthracite and bituminous coal and Kansko-Achinskiy deposit lignite with different carbon content were used. Experimental results were analyzed via three kinetic models: volumetric, shrinking core and random pore. The particle size distribution function was used as well. The obtained activation energy values are in good agreement with previously published data. The particle size distribution function implementation in reaction rate analysis allowed to increase a correlation coefficient value up to 0,9 for all models.
