在不同温度下热解高水分印尼褐煤并对所得半焦进行了氮气等温吸附测试和热重燃烧试验。结果表明：在热解温度为500~750℃的范围内，随热解终温升高，所得半焦的比表面积和总孔容会先减小后增大，并在650℃后基本维持不变；在相同的热解条件下，高水分印尼褐煤半焦的孔隙更加发达；随热解温度升高，半焦的最大燃烧失重速率先减小而后有所增加，在热解温度为600℃时达到最低值；半焦燃烧反应活化能则随着热解温度的增加持续增加。

The N2 adsorption isothermal and thermo-gravimetric analysis was carried out to study the char-acteristics of semi-coke generated by high-moisture Indonesia lignite at different pyrolysis temperatures. The results indicate that,within the pyrolysis temperature range of 500 ℃ to 550 ℃,the surface area and pore volume of the semi-coke decreased first and then increased,finally they leveled off at 650 ℃.Under the same pyrolysis conditions,the char derived from high-moisture Indonesia lignite had much more devel-oped pore structure than that from the lignite with low moisture.The thermo-gravimetric analysis suggests that,with an increase in pyrolysis temperature,the maximum weight loss rate of the chars during combus-tion decreased first and then increased a little,it reached the minimum value at about 600 ℃.The activation energy of the char during combustion increased with the pyrolysis temperature.
