煤的红外光谱研究

摘 要: 利用740型傅里叶变换红外 (FTIR)光谱仪系统地研究了褐煤与风化烟煤的红外光谱.结果表明:含碳量在一个较宽的范围内煤的红外光谱图相类似,从褐煤到烟煤,随着煤化作用的加 强,脂肪族C—H伸缩振动峰逐渐减弱,褐煤中存在大量原生腐植酸,烟煤中则含有大量再生腐植酸,这将为判断烟煤是否风化提出又一判据.根据煤的红外光谱还 可推测其所含腐植酸种类及含量.

STUDY ON INFRARED SPECTRA OF COALS

Abstract:In this paper, the infrared(IR) spectra from 4 000 to 400 cm -1 for brown and bituminou coal have been systematically studied by means of 740 model FTIR spectrometer. A similar basic skeleton for coals over a wide range of carbon content is indicated by the general similarity of the spectra. Due to the strengthening of coalification, the aliphatic C H stretching absorption bands of bituminous coal is weaker than that of brown coal. The brown coal contains a large amount of primary humic acid. The bituminous coal contains a large amount of regenerative humic acid, which will offer a standard for judging whether the coal was efflorescend. Humic acid type and content can be deduced by infrared spectra of coals. 

 

Key words: coal; IR spectra; efflorescence reaction; humic acid
