【摘要】 煤的岩相特性是决定煤质的关键因素 ,并会对煤的加工利用产生重要影响 .为了深入系统地研究煤岩显微组分的气化特性 ,综述了国内外对煤中各种有机显微组分的气化反应活性、气化反应动力学及气化反应活性与显微组分结构特性之间的关系等方面的研究进展 .多数研究发现 ,煤中各种有机显微组分的气化反应活性是不同的 ,但由于采用的实验煤样和实验条件等方面的差异 ,不同研究者得出的各显微组分气化反应活性的规律性较差更多还原

【Abstract】 The petrographical characteristic of coal is one of the key factors that influence the coal properties and conversion technologies.For better understanding of gasification of macerals,this paper presents a review of study on the reactivity,reactive kinetics during gasification and the relationship between reactivity and structure of every kinds of organic macerals in coal,that have been made by some researchers from domestic and abroad since the 1980s.General conclusion drawn from these studies is that gasification reactivity of every maceral is different and no definitive reactivity order was obtained at least under the used reaction conditions,due to their different experiment methods,reaction condition and coal samples.更多还原
