摘要：Abstract 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% Fe2O3 in 50 vol% H2O 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 H2 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 H2 evolution amount for co‐gasification with the addition of Fe2O3 was 152 mmol/g‐char. The increase in the co‐gasification for H2 evolution was based on a change in the char structure during pyrolysis and gasification.
