  • 摘要: 以市政污泥和玉米秸秆为原料，氯化锌为活化剂制备活性炭，采用BET、TG/DTG和DTA等方法对其性能进行分析。结果表明，秸秆添加量（质量比）为30%时活性炭吸附效果最好，热解分为水分析出、挥发分析出和终态稳定3个阶段，热解过程为放热反应，热解1 kg干基原料（秸秆质量比为30%）得到热解气、热解液和残炭的能量分别为1 880.49 kJ、8 354.22 kJ、2 301.84 kJ，剩余能量为11 502.53 kJ。
    Abstract: During the producing process of the activated carbon,municipal sludge and corn straw were used as raw materials,and ZnCl2 was used as an activator.Based on the results obtained from BET,TG/DTG and DTA processes,the activated carbon exhibited the best absorbility with a 30% mass fraction of corn straw.Pyrolysis which was an exothermic reaction process was divided into three stages:moisture evaporation,volatiles release and stability of final state.When 1 kg of dry raw material with 30% mass fraction of corn straw was pyrolyzed,it generated 1 880.49 kJ of pyrolysis gas,8 354.22 kJ of pyrolysis liquid,2 301.84kJ of pyrolysis coke and the residual energy was 11 502.53 kJ.
