摘　　要：采用热重分析仪对土霉素菌渣在氮气气氛下的热解特性进行实验研究，考查不同升温速率下土霉素菌渣的热重（TG）曲线和微分热重（DTG）曲线的变化规律。采用Coats—Redfem积分法对实验数据进行回归拟合，求出反应动力学活化能（E）和频率因子（A），并确定土霉素菌渣热解机理方程。结果表明：土霉素菌渣的有机物主要热解阶段为220～800℃；升温速率对菌渣热解影响不明显，随着升温速率的增大，试样的TG和DTG曲线向高温区移动，活化能E和频率因子A逐渐减小。The pyrolysis characteristics of terramycin experimentally studied using thermogravimetric analyzer bacterial residue with the presence of nitrogen were The variation of TG curves and DTG curves were examined under different heating rate. Apparent activation energy （ E）, frequency factor （A） and the mechanism equation of pyrolysis reaction were obtained by using Coats-Redfem integral method to fit experimental data. The experimental results shown that the mainly pyrolysis stage of organic meterial in terramycin bacterial residue was 220 -800℃. The effect to pyrolysis was not obvious by heating rate, as the heating rate increases, the TG and DTG curves of the sample move to high temperature region, the apparent activation energy （E） and frequency factor （A） gradually decrease.
