CO_2 gasification of iron loaded Yallourn coal, caron black and active carbon was carried out using a thermobalance. The sample was heated to 800℃ under Ar and then gasified with CO_2. When the sample was treated at 780℃〜800℃ with CO for 120s, rapid weight decrease was observed for selected samples. Such rapid gasification is considered to be due to the highly dispersed state of iron on carbon species.
