Abstract

The degree of coking or completeness of carbonization in the production of industrial cokes/chars is assessed with the help of appropriately corrected percentage value of residual volatile matter. Although coke reflectance has good correlation with final carbonisation temperature, its determination is time consuming. As CV:FC ratio has been shown to ascertain the degree of devolatilisation in heat altered coals, as well as in laboratory prepared cokes/chars it is worthwhile to consider its utility for assessing the degree of carbonisation in industrial coking practice too. Studies conducted on a range of industrial cokes/chars reveal that CV:FC ratio : (i) is directly related to residual volatile matter percentage, (ii) can differentiate between iso-volatile cokes/chars by assessing respective degree of coking and (iii) can indicate the order of final coking temperature reached even in cokes/chars having widely varying residual volatile matter percentage. It may, therefore, be inferred that CV:FC ratios provide a simple alternative route for assessing final coking temperature of industrial cokes/chars.
