摘要
研究了450℃下神东煤不同煤岩显微组分的加氢液化性能,从动力学角度探讨了其转化规律.结果表明:神东煤镜质组和壳质组的转化速率为惰质组的近2·6倍,镜质组和壳质组生成油和沥青烯的速率为惰质组的近2·9倍.未反应煤中主要是惰质组,镜质组和壳质组转化为油及沥青烯的比例高于惰质组.
Hydroliquefaction behaviour of Shendong coal macerals at 450 ℃ is studied,conversion rules of macerals are discussed by kinetics angle in this paper. The results show that conversion rate of vitrinite plus exinite is about 2.6 times than that of inertinite, oil and asphaltene generation rate of vitrinite plus exinite is about 2.9 times than that of inertinite. Unconverted coal is mainly inertinite,proportion of oil and asphaltene from vitrinite plus exinite is higher than that from inertinite.
