摘　　要：为了拓展煤气化残渣综合利用途径，进一步提高煤气化残渣的附加值，研究了宁煤集团3种煤气化残渣的物理、化学及矿物相的基本性质。研究结果发现气化残渣的真密度为2.24～2.68 g / cm3，其粒径主要集中在0.4～4.75 mm。此外，不同的煤气化技术及工艺造成气化残渣的残炭量差异较大，化学组成主要包括 SiO2（30%～51%）、Al2 O3（14%～19%）、CaO（8%～20%）、Fe2 O3（12%～23%）等，其晶相主要以非晶态玻璃体为主，其含量达到67%以上。基于气化残渣的基本特性研究其在建筑、防火、耐温等领域中应用的可能性，为气化残渣综合利用提供理论基础。In order to broaden the utilization ways of coal gasification residual and improve its added value,the basic characteristics of physical,chemical and mineral composition of three coal gasification residuals from Ningmei Group were studied. The results showed that, the true density of gasification residue ranged from 2. 24 g/ cm3 to 2. 68 g/ cm3 ,the diameter of most particles were between 0. 4 mm and 4. 75 mm. In addition,the amount of residual carbon oxides was effected by coal gasification technology and process. The content of SiO2 , Al2 O3 ,CaO,Fe2 O3 in residual fluctuated within the scope of 30% to 51% ,14% to 19% ,8% to 20% ,12% to 23% respectively. The a-morphous vitreous was the main crystal phase which accounted for above 67% . The feasibility research of coal gasification residual applica-tion in building,fire protect,temperature resistance and so on could find theoretical reference from the investigation of coal gasification re-sidual basic characteristics.
