Title: Nitrogen xanes studies of Argonne coals

Abstract

All the major forms of nitrogen in a group of Argonne coals are detected and quantified by X-ray Absorption Near-Edge Structure (XANES) studies; these forms are pyridine, pyridone, and pyrrole. In addition, there is evidence of aromatic and quarternary amines in small amounts, and virtually no saturated amines. Pyridone is found to be abundant in the low rank coals; with maturation of coals, the pyridone forms become transformed into pyridine forms. The quarternary nitrogen has been analyzed as a potential contribution to coal spectra. This compound has a distinctive peak in the nitrogen XANES spectra allowing contribution of quarternary nitrogen in the coal spectra to be determined. By this method we have found that coals generally have at most small quantities of quarternary nitrogen.
