| 摘 要： | 采用热重分析仪，对印度尼西亚油砂进行了燃烧特性试验。由热重DTG曲线可知，油砂燃烧过程分为4个阶段：燃烧低温、中温、过渡及高温段。采用“非对称高斯多峰拟合法”对油砂燃烧放热峰进行分离拟合，将实验DSC曲线复杂峰分离成为多个高斯函数峰。并结合Malek法确定了油砂燃烧时其伪组分的最概然机理函数。为油砂的有效开发与经济利用提供了理论依据。

| Abstract: | Experiments on combustion of Indonesian oil sands was conducted on thermogravimetric analyzer. The obtained DTG curves revealed that combustion reactions occurred at four different stages in all the samples: low-temperature，medium-temperature，transitional and high-temperature section. The experimental DSC peaks were effectively separated into multiple Gaussian peaks. At last，the most probable kinetic mechanism functions of oil sand pseudo-components were determined according to the Malek’s method，which provided theoretical foundation for further effective exploitation and economical application of oil sands. |
