摘要
对阳极热解挥发分组分氢气和甲烷的析出特性进行了研究。在小型固定床反应器上对生阳极样品进行了热解实验,考察了不同升温速率和不同阳极体积(重量)对挥发分氢气和甲烷析出的影响。结果表明:氢气和甲烷的析出都呈明显的双峰分布,峰值温度相差230℃左右;随着升温速率的增加,挥发分的析出速率加快,气体析出的峰值向高温侧移动,但两种气体的析出特征基本保持不变。应用高斯分峰法分别对氢气和甲烷气体的析出动力学进行了分析,得到了其释放的动力学参数。
Studied were the precipitation characteristics of anode pyrolysis volatile component hydrogen and methane.A pyrolysis test was performed of the anode samples on a miniature fixed bed and the influence of different temperature rise speeds and anode volumes(weights) on the precipitation of volatile component hydrogen and methane.The research results show that the precipitation of hydrogen and methane assumes a conspicuous dual-peak distribution and the temperature difference between the peak values is about 2...
