The Reactivity of Coke Texture

The reactivity of coke is one of the important properties considered as criteria of coke quality. The purpose of this work is to examine the relative difference of coke textures in reactivity.Some laboratory and metallurgical cokes before and after solution loss reaction were examined by quantitative analyses of anisotropic texture.The result was that(1) the isotropic texture from reactive maceral of low rank coal had the greatest reactivity and the reactivity decreased in the order of isotropic texture from reactive maceral, isotropic texture from inert maceral, fine mosaic texture, coarse mosaic texture and flow type texture and (2) the reactivity of coke texture from inert macerals as well as from reative macerals decreased with increasing in the coal rank.It was supposed that the various types of optical anisotropy found in coke was related to the action of coke in blast furnace.
