This study investigated the steam gasification of Indonesian Adaro coal and Japanese cedar mixed in a 1:1 ratio with the physical addition of 10 wt% Fe 2 O 3 in 50 vol% H 2 O at ambient atmospheric pressure and 800°C for 1 h. The primary objective of this work was to examine the effectiveness of an iron catalyst on the interaction between Indonesian Adaro coal and Japanese cedar. The study demonstrated that the H 2 evolution amount for co‐gasification of Japanese cedar and Adaro coal (with 1:1 ratio in weight) without a Fe catalyst was 100 mmol/g‐char. However, the H 2 evolution amount for co‐gasification with the addition of Fe 2 O 3 was 152 mmol/g‐char. The increase in the co‐gasification for H 2 evolution was based on a change in the char structure during pyrolysis and gasification.
