| 英文摘要 | The physiochemical properties of chars produced by coal pyrolysis in a laboratory-scale fluidized bed reactor with a continuous coal feed and char discharge at temperatures of 750 to 980 degrees C under N-2-based atmospheres containing O-2, H-2, CO, CH4, and CO2 were studied. The specific surface area of the char was found to decrease with increasing pyrolysis temperature. The interlayer spacing of the char also decreased, while the average stacking height and carbon crystal size increased at higher temperatures, suggesting that the char generated at high temperatures had a highly ordered structure. The char obtained using an ER value of 0.064 exhibited the highest specific surface area and oxidation reactivity. Relatively high O-2 concentrations degraded the pore structure of the char, decreasing the surface area. The char produced in an atmosphere incorporating H-2 showed a more condensed crystalline structure and consequently had lower oxidation reactivity.
