摘　　要：基于煤质与气化工艺性能的匹配性研究有利于气化工艺的有效选择,阐述煤炭气化工艺指标标准体系建立的重要意义,在研究现有气化用煤技术条件标准体系的基础上对其核心指标检测方法进行梳理,重点针对煤的热稳定性、煤对二氧化碳化学反应性、哈氏可磨性指数等3项工艺性指标的检测方法、检测标准、影响因素进行分析,以期为相关煤炭检测、技术研究等提供参考。根据灰成分、灰黏度、氟元素、氯元素和碱金属含量等指标对气化反应过程及设备产生的影响因素分析,可考虑将上述指标纳入完整的气化工艺用煤评价标准体系中。Based on that the study of matching between coal quality and gasification process performance is beneficial for selection of gasification process,the significance of establishing coal gasification process index standard system was demonstrated.Based on the existing standard system of coal technical conditions for gasification,the core index detection methods were sorted out,focusing on the detection methods,detection standards and influencing factors,three indicators such as thermal stability of coal,carboxy reactivity of coal,Hardgrove grindability index were analyzed,in order to provide reference for related coal detection and technical research.How the influencing factors caused by ash composition,ash viscosity,fluorine element,chlorine element and alkali metal content affected the gasification reaction process and equipment were analyzed,the above indicators can be considered to be included in the complete evaluation standard system of coal for gasification process.
