The efficient recovery and conversion of energy in oily sludge has great prospects. In this article, the main objective is to investigate the impact of the addition of CO during the pyrolysis of oily sludge on energy recovery and conversion by thermogravimetric analysis (TGA) and compare the effect with the traditional pyrolysis effect from the perspective of thermal conversion behavior, products composition, and kinetics analysis. The results of the experiment showed that in the CO atmosphere, the main weight loss temperature of oily sludge was mainly concentrated in the range of 300-500 °C, which is lower than the reaction temperature range of traditional pyrolysis. The yields of CO and H in the products have been greatly improved, and the highest proportion in the gas products can reach 19.29% and 22.38%, respectively. The (activation energy) values of oily sludge were determined to be in the range of 40-120 kJ·mol with the conversion between 0.2 and 0.8 via DAEM, KAS, Starink, and FWO methods, respectively, in which the FWO method has shown the strongest adaptability. The results of this study provide reference values for practical engineering applications.
油泥的能量高效回收和转化具有广阔的前景。本文主要目的是通过热重分析（TGA）研究 CO 在油泥热解过程中添加对能量回收和转化的影响，并从热转化行为、产物组成和动力学分析等角度与传统热解效果进行比较。实验结果表明，在 CO 气氛下，油泥的主要失重温度主要集中在 300-500°C 范围内，低于传统热解的反应温度范围。产物中 CO 和 H 的产率得到了很大提高，在气体产物中的最高比例分别可达 19.29%和 22.38%。通过 DAEM、KAS、Starink 和 FWO 方法分别确定油泥在转化率为 0.2-0.8 时的（活化能）值在 40-120kJ·mol 范围内，其中 FWO 方法表现出最强的适应性。本研究结果为实际工程应用提供了参考值。
