| 摘 要： | 基于TGA-FTIR联用技术,在线分析研究稻壳、稻秆及麦秆3种典型生物质在不同升温速率下的热解特性.分析生物质种类及升温速率对生物质的热解动力学参数及热解产物的影响.研究表明:由于生物质组成不同,其热失重特性也不同,生物质热解反应的活化能较低,为40～60 kJ·mol-1;红外分析表明试验用生物质热解过程中产物的析出规律相似,热解初始阶段先析出游离水,随后发生解聚和脱水反应,生成各种烃类、醇类、醛类和酸类等物质.随后,这些大分子物质又二次降解为一氧化碳为主的气体产物.

| Abstract: | The pyrolysis behavior of three typical agricultural residues,rice husk,rice straw and wheat straw was studied at different heating rates by thermogravimetric analysis(TGA)coupled with Fourier transform infrared(FTIR)spectrosco- py.The pyrolysis characteristics from different kinds of biomass at different heating rates were discussed.The results showed that the characteristics of products releasing are the same for the three samples during pyrolysis.The weight loss for different kinds of biomass from pyroly... |
