AbstractComparative studies on the Hailar lignite pyrolysis/gasification characteristics at N-2/CO2 atmosphere and the influence of inherent mineral matters, external ash and pyrolysis temperature on its reactivity during gasification at CO2 atmosphere were conducted by non-isothermal thermogravimetric analysis, FTIR, and X-ray diffraction (XRD) analysis. Thermogravimetric test results show that the atmosphere of N-2 or CO2 almost has no effects on the pyrolysis behavior, and the gasification reaction under CO2 atmosphere occurs over 943 K at the heating rate of 40 K min(-1). The external ash prepared at 1173 and 1223 K shows a certain catalytic effect on promoting the gasification reaction, although the inherent mineral matters of Hailar lignite are found in stronger catalytic effects on gasification than the external ash. The lignite gasification reactivity decreases with increasing pyrolytic temperature between 1073 and 1273 K.; Comparative studies on the Hailar lignite pyrolysis/gasification characteristics at N-2/CO2 atmosphere and the influence of inherent mineral matters, external ash and pyrolysis temperature on its reactivity during gasification at CO2 atmosphere were conducted by non-isothermal thermogravimetric analysis, FTIR, and X-ray diffraction (XRD) analysis.
