This chapter discusses X-ray photoelectron spectroscopy (XPS) and X-ray absorption near-edge spectroscopy (XANES) on coal and new findings for Spanish lignite. Gas chromatography-mass spectrometry is used for sulfur compounds in extracts from the coals. Sulfur- and nitrogen-containing compounds in coals are important because of the SOx and NOx emission problem during coal combustion and other problems, such as poisoning during catalytic processing, and instability during the storage of liquid products. The molecular and gross composition of the coal extracts corroborates the XPS and XANES data. No aliphatic sulfur compounds were detected in coal. Most of the organic sulfur in the extract of coal is present in aromatic groups.SulfurSulfurSulfur
