Yallourn brown coal was subjected to rapid pyrolysis at 500-900℃ with an entrained-flow pyrolyzer and a Curie-point pyrolyzer. The rapid pyrolysis was also conducted for the coals impregnated with iron precursors, ferrocene and ferric acetate. The micropore size distribution in the rapid pyrolysis char was determined by the molecular probe method using C0_2, C_2H_6, n-C_4H_<10> and i-C_4H_<10> and was compared with that in slow pyrolysis char. The heating-rate effect was evident on micropore size distribution as well as the product distributionand the elemental composition and He density of char. Micropores larger than 0.5nm in diameter did not exist in the rapid pyrolysis chars from the original coals. The iron precursors incorporated into the coals drastically changed the pore size distribution of the resulting char. For the iron-impregnated coal, the pore size was quite increased, and the volume of pores ranging between 0.5 and 1.0nm in diameter reached about 80wt% of the total pore volume, while the total pore volume was little changed.
