【摘要】 利用热重分析研究不同升温速率下3种生物质(核桃壳、花生壳和葵花籽壳)的热失重行为,采用Coats-Redfern法计算得到了3种生物质在不同升温速率、不同气氛下反应动力学参数。结果表明,3种生物质在热解主要阶段可由一级反应过程描述。更多还原

【Abstract】 The studies on three kinds of biomass(walnut shells,peanut shells and shell seeds) were obtained using TG and DTG curves at different heating rates.Kinetic parameters of three biomass were calculated at different heating rates and atmosphere with the method of Coats-Redfern.The results showed that the main pyrolysis process can be described by first order reaction model with the method of Coats-Redfern.更多还原
