Proximate analysis, ultimate analysis, Fourier-transform infrared spectroscopy (FT-IR), and thermogravimetry-differential thermal analysis characterization were carried out on oily sludge (OS) samples OS1-OS5, from Karamay, Xinjiang, China. The Coast-Redfern model (CRm) was used to simulate the pyrolysis and combustion kinetics of oily samples. The results showed that the peak area percentage of benzene ring trisubstitution of OS5, in the range of 700-900 cm, is close to 75%, corresponding to its high volatile content. Based on the kinetic analysis by the CRm, it is found that the fitting degree of the five samples is better when the reaction order is selected as = 2, with close to 1.00 and 2/ to 0. Among them, the and of OS5 are 17.8 × 10% min °C and 0.10899 × 10% min °C, respectively, higher than those of other samples, indicating a good combustion performance.
对来自中国新疆克拉玛依的油泥（OS）样品OS1 - OS5进行了元素分析、终极分析、傅里叶变换红外光谱（FT - IR）和热重 - 差热分析表征。采用Coast - Redfern模型（CRm）模拟油样的热解和燃烧动力学。结果表明，OS5在700 - 900 cm范围内苯环三取代的峰面积百分比接近75%，这与其高挥发含量相对应。基于CRm的动力学分析发现，当反应级数选为n = 2时，五个样品的拟合度较好，R²接近1.00且2/R接近0。其中，OS5的E和A分别为17.8×10% min °C和0.10899×10% min °C，高于其他样品，表明其燃烧性能良好。
