摘要： 依据胜利油田含油污泥的自身性质，以含油污泥的热重试验为基础，对比分析了含油污泥燃烧与热解的热重曲线，采用热重微商热重（TGDTG）法确定了不同升温速率条件下的着火温度和燃尽温度，利用CoatsRedfern积分法求解含油污泥的指前因子和表观活化能，并进一步分析升温速率对含油污泥燃烧特性的影响.结果表明：随着升温速率增加，燃烧速率、着火温度和燃尽温度不断提高，含油污泥的指前因子和表观活化能有所增大.

Abstract: The oil sludge’s combustion and pyrolysis TG and DTG curves were obtained through thermogravimetric analysis experiments on the properties of oily sludge from ShengLi oil field. The differences of combustion and pyrolysis thermal curves were analyzed. The TGDTG method was employed to determine the ignition and burnout temperatures at different heating rates.The differences of the ignition and burnout temperature and combustion characteristic index at different heating rates demonstrate that the heating rate has some impacts on the oil sludge combustion. CoatsRedfern integral model was adopted to obtain the combustion kinetic parameters including activation energy, preexponential factor and reaction order. The results show that, with the increase of the heating rate, the oil sludge’s combustion rate, the ignition and burnout temperatures of oily sludge, and the calculated value of oil sludge’s combustion kinetic parameters such as activation energy would increase.
