The pore structure is very critical and sensitive to react with CO2 in the case of cokes. But it is very difficult to detect the pore structure of cokes with nondestructive and high resolution because conventional porosimeter method can't detect macro pore (over 400 μm), and at the same time with destructive. We are at first demonstrating 3D-SPRITE imaging to detect the pore structure using SF4 gas, before and after CO2 reaction, (over 1 μm) with non destructive and the same pores, and then clarify the reaction mechanism. We found that the reaction rate of the cokes with CO2 depends on the pore size and the critical pore size is over 100 μm.
