煤显微组分结构特征及其与热解行为的关系
RELATIONSHIP BETWEEN STRUCTURAL CHARACTERIZATION OF MACERALS AND THEIR THERMAL BEHAVIOR
摘要
Abstract
XRD and FTIR have been applied to the investigatin of structural characterization of vitrinite and inertinite macerals of PS and SD coal,and the thermal devolatilisation behavior were seperated at heating rate of 20 °C/min by TG/MS. XRD spectrum revealed the similar structure as graphite of coal and the crastallite structural parameters were determined: d002(nm),dr(nm), Lc(nm),Ln(nm),Me and fa. The ratio of aliphatic hydrocarbon and aromatic hydrocarbon,the length of aliphatic hydrocarbon side chains and the substitutional condition of aromatic rings were determined by FTIR. This study reveals the rich hydrogen condition, aliphatic hydrocarbon side chains linking condition and the substitutional condition of aromatic rings of the sample. The TG and the thermal devolatilisation behavior have relation with the characterization of coal structure. The thermal devolatilisation behavior and generation mechanism of C1-C4 light hydrocarbon, hydrogen, benzene and phenyl were specially analyzed.关键词
