The paper describes study of influence of coke structure on the reactivity and strength. Porosity of six cokes was observed by microscope analysis and results were compared to reactivity and strength after reaction with CO2. The result of this observation acknowledge dependence between coal properties, charge preparation (charge of one coal, blend of coals), coke texture (inert material), important coke properties as strength, reactivity and porosity.
