Formatted abstract
In order to study the influence of anthracite, char, coke and graphite microstructures on reactivity, a thermogravimetry experiment was carried out for these carbons at 1200 °C. As a comparison, some experiments were conducted at 1600 °C. The microstructure of anthracite, char, coke and graphite after treatment was depicted by SEM. The results showed that reaction of char 1, CA 3 and coke 5 in CO2 gas at 1600 °C led to a large, smooth pore structure, in contrast to the carbons’ reaction at 1200 °C. The porosity of all carbons increased with reaction time and the porosity of graphite was far less than the other carbons. Besides, the variation of porosity determined the value of the reactivity. An appropriate carbon type can be chosen based upon reactivity for pulverized coal injection in a blast furnace.
