In cokemaking process, understanding on pore formation through melting behavior of coal is important to control coke pore structure and strength. However, in-situ observations of pore formation have never been achieved due to various difficulties. Instead, the pore formation has been estimated based on cross-section observation of quenched samples. In this work, synchrotron X-ray imaging was applied during a carbonization test to observe the pore formation in situ. The images of pores were successfully obtained every 0.4 degrees Celsius without quenching. This in-situ imaging technique potentially contributes to the clarification of coking process of coal and the improvement of techniques to control the coke quality.
