STUDY ON CHEMICAL STRUCTURE EVOLUTION AND REACTIVE MECHANISM OF BIOMASS CHAR PREPARED IN CO2/H2O ATMOSPHERE

  • 摘要: 以水稻秸秆(RS)为研究对象,研究了CO2/H2O气氛对其脱挥发分过程中焦产率、结构及其反应性的影响。采用傅里叶红外光谱(FTIR)及拉曼光谱(Raman)对不同条件下制备的RS焦进行表征,阐明不同反应气氛下RS焦的微观化学结构演化规律。采用热重分析仪(TGA)对制备的RS焦的燃烧反应性进行分析,揭示了CO2气氛、H2O气氛与CO2/H2O混合气氛对RS焦微观化学结构演化及反应性的作用机理。结果表明:CO2/H2O气氛下,生物质焦产率随着反应终温升高而降低,且在700 ℃以上焦产率差异较大;CO2/H2O混合气氛更有利于促进生物质焦中小芳香环系统的消耗和缩聚,CO2和H2O气氛在高温下对生物质焦的反应存在协同作用和竞争关系;制焦温度在700 ℃以上时,CO2/H2O气氛有助于改善生物质焦的燃烧特性。
