摘要：
Temperature-programmed pyrolysis of SL-lignite from Xilinhaote was investigated. The solid and gaseous pyrolysates were analyzed by means of gas chromatography(GC) and X-ray diffraction(XRD). The weight percents of surface moisture, ash, C, H and S increase with increasing the pyrolysis temperature in solid pyrolysates, while the volatile matter is contrary. The cracking reaction occurs before 600 degrees C, the consolidation reaction happens between 600 degrees C and 650 degrees C, while the polycondensation or secondary reaction appears after 650 degrees C. Calcium sulfide is formed by the process of decomposition of calcium sulphates at 900 degrees C. The solid pyrolysates become more graphitic with increasing the pyrolysis temperature.
