| Abstract: | The microstructure of Dayan brown coal, Huangxian brown coal and their chars produced in an experimental apparatus using char as solid heat carrier is analyzed using the CO2 adsorption method at 298 K. For each type of coals and chars, specific surface area, micropore volume, micropore effective surface area, mean equivalent radius of micropores and micropore volume distribution are determined, and their variations with carbonization temperature are studied and discussed. |
