Abstract

The microtextural characteristics of coke, prepared form twelve Indian coking/caking coals were studied. The coke carbon forms are classified into reacted (binder phase) and inert (filler phase) categories. It has been observed that the proportion of different reacted material is related to the vitrinite reflectance types of the parent coal. In general, with increasing vitrinite reflectance the degree of anisotropism and domain size of carbon forms increase, but due to the highly intermixing nature of reactive microcomponents with inerts (of Indian coals) they create smaller-sized domains. This type of coke analysis is quite useful for the assessment and comparison of cokes. The carbon form classification described here may be employed successfully in the characterization of coke and their relationship to parent coal rank and type. This technique will also be helpful in solving different plant problems like determination and checking of proper blend proportions, quality of coal, etc.
