摘　　要：利用固定床反应装置,以CO_2为气化剂研究了无烟煤和烟煤配煤气化反应的特性,考察了反应温度(900℃~1 100℃)和掺混量对气体产物及CO_2转化率的影响,采用SEM对煤焦表面进行分析。结果表明:烟煤焦的孔隙结构比无烟煤焦发达,在相同温度下,烟煤焦气化活性高于无烟煤焦。混煤的气化活性近似线性增加,在无烟煤中配入烟煤可以有效地改善煤质,提高气化活性。Using CO_2 as gasifying agent to study on gasification characteristics of anthracite, bituminous and their blends in a fix-bed reactor. The effect of temperature（900 ℃ ~1 100 ℃） and blending weight on gas products and CO_2 conversion rate were investigated, the chars were analyzed by scanning electron microscopy（SEM）. The results indicated that bituminous char appears more pore sturcture.The reactivity of bituminous char was higher than anthracite char. The reactivity of blended coal seeming to increase linearly. Blending bituminous with anthracite can effectively improve coal quality and gasification reactivity.
