本研究探讨了火鸡羽毛热解的热效应和化学效应。由于羽毛产量的不断增加和利用的困难，羽毛的热解研究具有重要意义。实验采用热重分析（TGA）、差示扫描量热法（DSC）和两台热解反应器进行。实验研究表明，羽毛材料在210至240摄氏度之间的温度下会分解。这种液化与羽毛的各种分散和多孔元素聚集成更大的液滴一起导致体积减小。此外，本工作还介绍了在不同温度下热解火鸡羽毛的固体、液体和气体产物的组成特征。在900摄氏度的温度下，气体产物的较高热值（HHV）等于19.28 MJ/Nm（3），使得气体适合用作燃料。火鸡羽毛的热化学转化导致在液体（0.13%）和气体（88 mg/Nm（3））产物中形成有毒化合物，例如氰化氢（HCN）。羽毛液化的现象很重要，因为它会导致反应器壁的快速降解和沉积物的形成。(C)2016爱思唯尔有限公司版权所有。
This study examines the thermal and chemical effects of the pyrolysis of turkey feathers. Research of feathers pyrolysis is important because of their increasing production and difficulties of their utilization. The experiments were carried out by means of thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and two pyrolytic reactors. The experimental investigation indicated that the feather material liquefies at temperatures between 210 and 240 degrees C. This liquefaction together with the agglomeration of various dispersed and porous elements of the feathers into larger droplets leads to the volume reduction. Moreover, this work presents characteristics of the composition of the solid, liquid and gaseous products of turkey feathers pyrolysis at different temperatures. The higher heating value (HHV) of gaseous products in temperature 900 degrees C equals 19.28 MJ/Nm(3) making the gases suitable for use as a fuel. The thermochemical conversion of turkey feathers leads to the formation of poisonous compounds such as hydrogen cyanide (HCN) in the liquid (0.13%) and gaseous (88 mg/Nm(3)) products. The phenomenon of liquefaction of feathers is important because it can lead to rapid degradation of the walls of reactors, and the formation of deposits. (C) 2016 Elsevier Ltd. All rights reserved.
