The effect of pyrolysis pressure (0.02 kPa and 0.99 MPa) and N_2/CO_2/O_2 concentration was investigated on CO_2 gasification reactivity of biomass-derived char. The BET surface area of chars produced at 0.02 kPa increased from 275.4 to 417.1 m^2/g by addition of CO_2/O_2 to N_2 and with increasing O_2 concentration. The physical properties of char produced at 0.99 MPa were independent of CO_2/O_2 concentration and were almost 3 to 4 m^2/g. The kinetic constant (K_p) of CO_2 gasification of char produced at 0.02 kPa under N_2/CO_2/O_2=18/41/41 was twice as that produced under N_2 and was approximately three times as those at 0.99 MPa.
