Abstract
在热天平分析仪上对比分析了玉米芯水解残渣、玉米芯及残渣木质素的热失重特性,借助TGA-FTIR解析了残渣木质素热解过程中主要产物的析出特性,在自制小型快速热解装置上对比考察了水解残渣和玉米芯的热解产物分布,并进一步对比分析了热解气的组分组成及热解焦的气化反应性。TGA结果表明,玉米芯热解主要集中在250~450℃,而水解残渣和残渣木质素的热解温度范围为180~800℃。TGA-FTIR分析显示,甲醇和酚类的主要析出温度区间为200~420℃,而CO和CH4主要在400℃以后析出。在热解温度550~850℃内,水解残渣的固体热解焦产率为30.35%~42.64%,远高于玉米芯热解的固体产率19.18%~26.40%,且残渣热解焦的气化反应性低于玉米芯热解焦;气体组分中CO和CO2产率较高,H2产率在温度高于650℃时明显提高
