Abstract The reactivity of coke is affected by the pore structure and the coke matrix. Ten kinds of coke were crashed into powder to study the reactivity of the coke matrix. The differences in the coke matrix were found to affect their reaction performance. The relationship between coke structure and reactivity was studied by Raman test and peak fitting of the spectrum. In the experiment, the Raman spectrum was divided into five peaks: D1, D2, D3, D4, and G. The reactivity of cokes showed a good correlation with the peak area ratio of D4 and G. The cokes with more random structures showed a higher reactivity in the corresponding time. A good correlation between the optical textures content and Raman peak area ratio of coke was also found.
