Abstract
For the purpose of finding a quality of coke, the reactivity test were carried out. At first the influences of the reaction temperature, particle size of coke, reaction time and gas velocity were examined with a favourable apparatus to measured the rate of C+CO2-2CO reaction, and then the reactivities of cokes were measured under the adequate conditions. It was suggested from the results that the reactivity of coke is possible to calculate or presume from the basic value of ingredient coal reactivity and mixing ratio of individual coal.
