| 摘 要： | 对淄博、滕县两煤田不同煤级与腐植煤共生的腐泥煤系列进行了对比研究。红外光谱特征为：反映芳环－Ｃ＝Ｃ－键伸缩和弯曲振动的１６００ｃｍ－１峰的吸收值都小于共生腐植煤；反映芳烃ＣＨ基团面外弯曲振动的８８０ｃｍ－１峰只在腐植煤中出现，而８１０ｃｍ－１峰的吸收值全部高于腐植煤；两次出现了在腐植煤中从未出现过的８１０ｃｍ－１＞７５０ｃｍ－１的情况；芳烃结构指数＞０８，而腐植煤则全部＜０８。Ｘ线衍射结果：ＬＣ都随煤化作用的进行逐渐增大，在Ｃｄａｆ为９２％±达峰值，然后又逐渐变小；两个系列相比，全都是腐泥煤较大；Ｌａ都随煤化作用的进行逐渐增大，大部分腐植煤比腐泥煤的大；ｄ（００２）都随煤化作用的进行逐渐变小，两个系列相比都是腐泥煤的较小。

| Abstract: | Sapropelic coal series common existing with humic coal have been contrastive studied for different ranks coal in two coalfields of Zibo and Tengxian. The infrared spectrum charateristics is: Absorptive values responsing expand and contract and bending vibration of aromatic ring -c=c- bond at 1600cm -1 peak are all smaller than that of co-existing humic coal, it appears only in humic coal that peak 880cm -1 of bending vibration responsing aromatic hydrocarbon CH bassmass. Absorptive value at peak 880cm -1 are all larger than that of humic coal, meanwhile, the situation never happening in humic coal appears two times, peak 810cm -1 larger than peak 750cm -1 , aromatic hydrocarbon construct index is large 0 8, but humic coal is all smaller than 0 8. The results of X-ray diffraction are: L e increases gradually with colification enhancement, and reaches to peak at 92% C daf , then decrease gradually. Two series compare, sapropelic coal is always large, L a always increases gradually with coalification enhancement, the most of humic coal larger then metamorphic coal D(002) become alwayes smaller gradually with colification, comparing two series, metamorphic coal is always smaller. |
