| 摘 要： | 燃烧动力学是研究油页岩半焦颗粒燃烧特性的基础。利用热重分析仪对油页岩半焦进行了恒温燃烧实验研究，在排除外扩散影响的基础上，分析了燃烧温度、氧气浓度对油页岩半焦燃烧过程的影响。在实验范围内，氧气浓度和燃烧温度均能对油页岩半焦燃烧速率产生重要影响，更高的氧气浓度和燃烧温度可以加快油页岩半焦燃烧速率。结合实验结果，建立了考虑氧气浓度影响的油页岩半焦燃烧动力学模型，发现油页岩半焦燃烧速率与氧气浓度的0.97次方呈线性关系。模型计算结果与实验结果符合较好，为进一步研究油页岩半焦大颗粒燃烧特性提供了燃烧动力学基础。

| Abstract: | Combustion kinetics is the basis for studying the combustion characteristics of oil shale semi-coke particles. Thermal gravimetric analyzer (TGA) was used to conduct isothermal combustion experiments of oil shale semi-coke. Effects of combustion temperature and oxygen concentration on kinetics of oil shale semi-coke combustion were analyzed. Higher combustion temperature and oxygen concentration would lead to faster combustion rate. A kinetic model considering oxygen concentration effects was developed. It was found that the combustion rate of oil shale semi-coke is proportional to oxygen concentration to the 0.97 power. The kinetic model yielded good agreements with the experiments results, and could provide a base for further investigation on the combustion of large oil shale semi-coke particles. |
