摘 要: | 目的]利用热重-质谱联用(TG-MS)技术,分析了棉秆在催化条件下的热解过程.方法]采用活化热解区与消极热解区法、热解特性指数法,比较了CaO、MgO对棉秆热解的影响,通过质谱分析研究了CaO、MgO对棉秆热解过程中焦油组分析出的影响.结果]CaO、MgO对棉秆的活化区和消极区均有催化作用,且CaO、MgO对棉秆的挥发分析出特性具有改善作用;棉秆热解产生的焦油组分主要为苯、甲苯、苯酚,CaO、MgO的加入使焦油组分的析出温度范围变窄、离子强度下降.结论]该研究为棉杆的催化热解研究提供了科学参考.

Abstract: | Objective] Catalytic pyrolysis characteristics of cotton stalk were studied with TG-MS analyzer.Method] By using the active and passive zone as well as pyrolysis index,the influences of CaO and MgO on the pyrolysis characteristics and the tar evolution during the heating processes were discussed.Result] CoO and MgO had catalytic effects on both the active and passive pyrolysis zone of cotton stalk; CaO and MgO promoted the precipitation of the volatiles ; the mass spectrometry analysis showed that the main components of tar were benzene,toluene and phenol; CaO and MgO narrowed the temperature range of the tar precipitation and reduced the peak values of the tar components.Conclusion] The research could provide scientific references for the catalytic pyrolysis of cotton stalk in future. |
