摘　　要：这是一篇矿物加工工程领域的论文。气化渣是煤气化过程中产生的副产物,较难进行工业化处理。为实现对气化渣的合理有效利用,对我国鄂尔多斯地区典型的水煤浆工艺所产的气化粗渣进行简单的筛分处理,将其分为高、中和低碳三类碳渣。利用XRF、元素分析仪、XRD、SEM、BET比表面积分析仪、热重分析仪和ICP-MS等分析设备对三类碳渣的物理化学性质、重金属含量、碳含量、微观形貌、矿相组成和孔隙结构等进行表征分析。高、中和低碳三类碳渣具有显著的性质差异,筛分作业能较好地实现了气化渣的初步分质,为气化渣的利用奠定了基础。This is an article in the field of mineral processing engineering.The gasification slag is a byproduct produced in the process of coal gasification,which is difficult to be industrialized.In order to realize the rational and effective utilization of gasification slags,the gasification coarse slags produced by the typical coal water slurry process in Ordos area of China are simply separated into high,medium and low carbon slags by screening.The physicochemical properties,heavy metal content,carbon content,micro morphology,mineral phase composition and pore structure of the three types of carbon slags were characterized and analyzed by XRF,element analyzer,XRD,SEM,BET specific surface area analyzer,thermogravimetric analyzer and ICP-MS.The high,medium and low carbon slags have significant differences in characteristics.The screening can better realize the preliminary quality separation of gasified slags,which lays a foundation for the classified utilization of gasified slags.
