Title: | Studies of the soluble part of oxidised coals | Authors: | PIETRZAK, Robert Kozalowski, M Wachowska, H YPERMAN, Jan |
Issue Date: | 2004 | Publisher: | CENTRAL EUROPEAN SCIENCE JOURNALS | Source: | CENTRAL EUROPEAN JOURNAL OF CHEMISTRY, 2(2). p. 278-289 | Abstract: | Soluble products obtained from the oxidation of four types of coal, each characterised by different degree of coalification and different degree of sulphur content, are studied. The coals are oxidised with peracetic acid (PAA) and nitric acid. Analyses are performed by Atmospheric Pressure-Temperature Programmed Reduction (AP-TPR) and Fourier Transform Infrared Spectroscopy ( FTIR). The soluble products contain much more sulphur than the insoluble products of oxidation. The products obtained from the reaction with HNO3 contain higher amounts of inorganic sulphur compounds, while those obtained from the reaction with PAA are characterised by an increased content of organic sulphur species.
