Abstract

A high-temperature coal tar (HTCT) was sequentially extracted with petroleum ether (PE), ethyl acetate (EA), and acetone with ultrasonic irradiation to afford extracts 1 to 3 (E1 to E3), respectively, and acetone residue. The gas chromatography/mass spectrometry (GC/MS) analysis of all extracts show that E1 is mainly composed of di- and tricyclic arenes such as naphthalenes, phenanthrene, anthracene, etc., whereas high contents of heteroatomic compounds and four or more ring arenes were found in E2 and E3, respectively. The pyrolysis process of acetone residue was studied with a thermogravimetric (TG) analyzer equipped with Fourier transform infrared (FTIR) spectrometer. The results indicate that volatiles were mainly released at 380–560 °C, and the maximum mass loss rate occurred at 492 °C.
