The Effect of Minerals on the Reactivity of Coal Char Treated Thermally

Abstract The effect of minerals on the reactivity of coal char is addressed in this article. The chars were prepared in N2 under the inert conditions from the raw coals and their demineralized samples. Thermo-gravimetric analysis (TGA) was used to examine the effect of the minerals in the coals on the reactivity of the derived chars. The effect of minerals on the reactivity of YXV char is different from that on the reactivity of JJV char. The behavior of minerals differs from each other and can be attributed to the different amount, nature, and distribution in the two coals.
