【摘要】 用热重分析仪对秸杆类生物质的热解行为进行了热重分析 (TG)和差分热重分析 (DTG)。试验中利用程序升温法对物料进行加热升温 ,加热速率分别为 10 K/ min,2 0 K/ min和 30 K/ min;加热终温为 1173K;样品料径为2 5 0～ 10 0 0 μm,高纯氮气做保护气。通过对 TG、DTG曲线分析 ,研究了加热速度、温度、加热时间等对热解过程的影响 ,给出了热解反应动力学参数。结论对秸秆类生物质的再利用技术研究和装置的优化有重要的指导价值更多还原

【Abstract】 This paper presents parts of experimental results of agricultural residues pyrolysis under high purify N 2 using thermogravimetric analysis technique.In the experiments,the heating rates are 10 K/min,20 K/min,30 K/min respectively;heating end temperature is 1 173 K;the diameter of sample is 250 μm～1 000 μm.TG and DTG analysis techniques are adopted to systematically study the pyrolysis behavior of agricultural residues.The effects of heating rate,time and temperature on pyrolysis process were concluded.A proper pyrolysis mechanism of pyrolysis was proposed.The kinetic parameters of agricultural residues pyrolysis were given.These conclusion are useful for the reuse of the agriculturual wastes.更多还原
