The CO_2 gasification behavior of biomass chars, derived under N_2/CO_2/O_2 atmosphere at 800℃, were investigated at 800 - 1000℃ under 0.02 kPa and 1.0 MPa atmosphere using Random pore model (RPM). The CO_2 gasification rate constant (K_p) of chars derived at 0.02 kPa increased with the BET surface area and exhibited as 1.5-3.2 times as those derived at 1.0 MPa. K_p at 900℃ of char derived at N_2/CO_2/O_2=18/41/41 vol% was as 1.7 - 2.5 times as those of char under the other atmosphere. K_p increased with an increase in the BET specific surface area, and especially the char derived at N_2/CO_2/O_2= 18/41/41 vol% had maximum values of 417.1 m^2/g of BET specific surface area and 0.3 min^<-1> of K_p, respectively.
