Results show that the process of 重的环境污染问题。所以有必要寻求准东煤合理环 Zhundong coal pyrolysis can be described by three stages, which are evaporation and dried of water, combustion of the 保的利用方式。煤气化作为一种重要的洁净煤技 volatile and polycondensation; the pyrolysis process finished 术，具有广阔的发展前景。国内外的许多学者对煤 basically when pyrolysis temperature was higher than 800 ℃; 的热解特性和气化活性进行过较为深入的研究。杨 as the increase of heating-up rate, the maximum weight loss 泱等[3]总结了影响煤热解、气化的主要因素。对于 rate and pyrolysis index D increased; increase in the
