Abstract

Fourier transformation infrared microspectroscopy ( Micro-FTIR)isone of effective waysfor identify-ing the chemical structure. Based on the high-purity coal macerals separating and concentrating,in this paper, Mi-cro-FT IR technique was used to investigate the chemical composition and structuresof alginite, sporinite, cutinite,desmocollinite and fusinite from Jurassic coalsin Tu -ha basin. The results show that the chemical structure of aligi-nite and sporinite are mainly composed of long aliphatic -side chain, and minor amounts of aromatic compounds. Cutinite and desmocollinite are mostly composed of aromatic compounds,in addition to large amount of aliphatic compounds. Whereas fusinite are dominant by aromatic structure. These indicate that aliginite and sporinite are one of the best oil source-rocks, with the highest hydrocarbon generation potential; cutinite and desmocollinite are also the better oil and gas source-rocks, and have higher hydrocarbon generating potential; fusinite has little hydro-carbon-generating potential. Desmocollinite is one of the most amount of macerals in Jurassic coals in Tu-ha basin,so it is one of the most important macerals for contribution to oil from coals in Tu-ha basin.
