In this research, the effect of different clay minerals (bentonite, illite and kaolinite) on the combustion behavior and kinetics of crude oils from Kazan region (Russia) was studied using thermogravimetry (TGA) and differential scanning calorimeter (DSC). The ramped temperature experiments were performed at constant heating rates (10, 20 and 30 °C/min) under air atmosphere. In both TGA and DSC experiments, two reaction zones were identified known as low temperature oxidation (LTO) and high temperature oxidation (HTO). The reaction regions, burn-out temperatures, mass loss, heat of reaction and peak temperatures were determined. It was observed that the reaction intervals and the peak temperatures were also affected in the presence of different clay minerals. Kinetic parameters were calculated by Ozawa-Flynn-Wall (OFW), Kissenger-Akahira-Sunouse (KAS) kinetic methods. The addition of different clay minerals reduced the mass loss percentages of the crude oil samples due to the surface area effect. In addition, all clay samples show a good catalytic effect by a significant reduction in activation energy.

在这项研究中，使用热重分析（TGA）和差示扫描量热仪（DSC）研究了不同粘土矿物（膨润土，伊利石和高岭石）对喀山地区（俄罗斯）原油燃烧行为和动力学的影响。在空气气氛下以恒定的加热速率（10、20和30°C / min）进行升温实验。在TGA和DSC实验中，确定了两个反应区，称为低温氧化（LTO）和高温氧化（HTO）。确定反应区域，燃尽温度，质量损失，反应热和峰值温度。观察到在存在不同粘土矿物的情况下，反应间隔和峰值温度也受到影响。动力学参数由Ozawa-Flynn-Wall（OFW）计算，Kissenger-Akahira-Sunouse（KAS）动力学方法。由于表面积效应，添加不同的粘土矿物降低了原油样品的质量损失百分比。此外，所有粘土样品均通过显着降低活化能显示出良好的催化作用。
