Fourier Transform Infrared Spectroscopic Analysis of the Raw and Tectonic Coals Extracts with Ultrasonic

Abstract:

Zouzhuang coals were extracted by chloroform under ultrasonic irradiation. The qualitative and quantitative characterization of the extracts that gained in each fraction was analyzed with Fourier transform infrared spectroscopy. The experimental results show that the extraction rate of tectonic coal (5.1%) is more than twice as compared to that of raw coal (2.2%). The extraction process of tectonic coal can be divided into four phases; however, there are only two stages for raw coal (all phases followed one order reaction kinetic equation).The diffusion behavior of two kinds of coal extract is distinct, the rate of free and adsorbed states were rapid, while, the stripping of eutectic state is slightly slow. The content of Aromatic C=C skeletons is similar to that of individual aromatic hydrogen atoms replaced. The content of-OH /-NH associated by hydrogen bonds is poor and the content of aromatics with two or four substituents is relatively higher. The content of saturated and aromatic hydrocarbons of tectonic coal is close to that of raw coal. Non-hydrocarbon content in tectonic coal is lower than that of raw coal, the content of asphaltene of tectonic coal, on the contrary, is higher than raw coal.
