该文分析了生物半焦制备过程中热解温度、热解速率等条件对生物半焦吸附性能的影响。结果表明随热解温度升高，比表面积及孔隙结构呈现先增大后减小趋势，快速热解获得比慢速热解更好孔隙结构。通过活化和脱灰方式对半焦进行改性，改性后的半焦具有更好的吸附性能，也称为活性半焦。生物质活性半焦用于处理染料废水和烟气脱汞等。

The effects of pyrolysis temperature, pyrolysis rate and other conditions on the activity of biomass char in the process of biomass char preparation were analyzed. The results showed that surface area and pore structure firstly increased and then decreased with the increase of the pyrolysis temperature. The pore structure was better under quickly pyrolysis than slowly pyrolysis. Biomass char can have the better adsorbability by modified and deashing that was called activated char. Biomass activated char were applied on dye wastewater treatment and flue gas demercuration.
