Abstract

DSC/TG in hyphenation with FTIRS and MS was applied to the study of pyrolysis of coal mined in Xinjiang. As shown by the experimental results, significant mass loss of the coal sample was observed in the temperature interval of 350 ℃ to 650 ℃, the rate of mass loss attained to 1.3%·min-1 at 447.0 ℃; the coal was coked at 950 ℃. It was shown by the results of FTIR-MS that CO2, CH4, H2O and CO are the main gaseous products liberated during the course of pyrolysis of coal sample. Besides, low contents of sulfur in the coal sample was liberated as SO2 from 300 ℃ to 400 ℃.
