【 摘 要 】

Four kinds of pulverized coal samples from China and Indonesia were studied by thermogravimetry coupled with mass spectrometry and fourier transform infrared spectroscopy (TG-MS-FTIR). The thermal behaviors and gaseous emissions of these coals were analyzed in this work. The results indicate that the relative lower values of H/C ratios, which normally represent the degree of aromatization and ring condensation in coal samples, could lead to the relative more intense thermal reaction. The time-evolved profiles of some typical gas products (i.e., CO, SO2, CH4, NO, NO2, NH3and etc.) were provided by TG-MS-FTIR, and their variations are different. For all the samples, the releases of SO2and COS can be found at lower temperature than those of NO and CO. As the temperature increases, the possible conversion of NO2and NH3to NO is deduced in this work.
