Geochemistry of Sulfur in Extract from Hedong Coal Mine, China

Abstract:

The organosulfur compounds in the extract of the unusually organic sulfur rich of Hedong coal mine had been identified by gas chromatography and mass spectrometry. There are two series organosulfur compounds (OSC) were detected in the extract, they are benzonaphthothiophen and dibenzothiophene and the content of methylbiphenyl is overwhelming advantages in the biphenyl series. It demonstrates that the coal was formed in alkaline environment. The coal was formed in a reduction environment generally but there are exceptions, the samples HD9-2 and HD10-13 which have the value of Pr/Ph was 3.52 and 4.05 and So/St in sample HD9-2 was 78.82%, 73.08% in sample HD10-13 respectively . It show that the coal suffer strong oxidation and there are no good correlation between the content of organic sulfur and the oxidation environment.
