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。
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
