Effect of Fe2O3 on steam gasification of subbituminous coal/woody biomass mixture

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 degrees 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 Fe2O3 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.
