本文对比研究了典型木质纤维生物质和非木质纤维索类生物质的轻度热解特性,并基于多步反应动力学原理,建立了生物质轻度热解的两步反应动力学模型。结果表明:在同样的停留时间下,木质纤维类生物质的失重明显大于非木质纤维类生物质的;两步反应模型能够很好地预测两类生物质的轻度热解过程,并能预测得到平衡失重百分比。 This paper comparatively studied the mild pyrolysis characteristics of typical lignocellulosic biomass and non-lignocellulosic biomass, and established a two-step reaction kinetic model for light pyrolysis of biomass on the basis of multi-step reaction kinetics. The results showed that under the same residence time, the weight loss of lignocellulosic biomass was significantly greater than that of non-lignocellulosic biomass. The two-step reaction model could predict the mild pyrolysis of two types of biomass well and could predict Get a balanced weight loss percentage.
