摘要
[目的]明确水葫芦的热解特性.[方法]采用热重分析方法对滇池中的水葫芦进行热解试验,绘制水葫芦叶、根、整株的热重曲线.[结果]水葫芦热解从易到难的顺序为整株、叶、根,整株水葫芦在289 ～531℃的热解失重率为35.52％,叶在279 ～497℃的热解失重率为54.11％,根在288 ～488℃的热解失重率为40.88％.[结论]试验结果为水葫芦的燃料和发酵利用提供了参考.
Abstract
[Objective] To study the pyrolysis characteristics of Eichharnia crassopes.[Method] The pyrolysis experiment of E.crassipes in Dianchi Lake was carried out by using the method of thermal gravimetric analysis.The heat and weight curve of the leaf,root and whole plant was obtained.[Result] E.crassipes pyrolysis from easy to difficult was in the order of whole plant,leaf and root;the weight loss rate of the whole E.crassipes at 289-531 ℃ was 55.52％,the weight loss rate of the leaf at 279-497 ℃ was 54.11％,the weight loss rate of the root at 288-488 ℃ was 40.88％.[Conclusion] This research provides references for the burning and fermentation utilization of E.crassipes.
