摘　　要：借助对称因子法对复杂的ＴＰＲ图谱（如拖尾、重叠峰等）进行了详细的分析，以Ｄ－Ｍ分布函数描述ＴＰＲ峰高和还原温度之间的定量关系。采用多维搜索及线性回归的方法对ＴＰＲ图谱进行了解析，估算了Ｎｉ－Ｗ／Ｆ－Ａｌ２Ｏ３－ＳｉＯ２催化剂的程序升温还原反应动力学参数。In this paper,the complex TPR curves with tailing or overlapping were analyzed.The D-M distribution function was used to describe quantitatively relation between peak height of TPR curve and temperature. Based on experimental results, some kinetic parameters of TPR of NiO-WO_3/F-Al_2O_3-SiO_2 catalyst, such as activation　energy, frequency factor and order, were estimated.
