In this study, the gasification of bio-char was activated by using a catalyst (Fe), which is a typical alkali metal. In addition, the gasification mechanism of bio-char, on which Fe was loaded, was examined by analyzing the pore development (by measuring the specific surface area, the pore diameter) and random pore model. The results obtained in this study are as follows: (1) when Fe was loaded on bio-char, although there were closed-pores in the initial stages of gasification, pores rapidly developed with the increase in carbon conversion; (2) Rapid development of the pore diameter leads to suppress the development of the specific surface area and the gasification rate after the second half (X=0.5‐) of gasification.
