Title: | Effect of calcium and calcium minerals in coal on its thermal analysis | Authors: | MAES, Inge GRYGLEWICZ, Grazyna YPERMAN, Jan FRANCO, Dirk MULLENS, Jules VAN POUCKE, Lucien |
Issue Date: | 1997 | Publisher: | ELSEVIER SCI LTD | Source: | FUEL, 76(2). p. 143-147 | Abstract: | The effect of the presence of limestone and dolomite in coal, and calcium in lignite, on atmospheric-pressure temperature-programmed reduction (AP-TPR) analysis was studied. AP-TPR experiments were carried out on a bituminous coal with added limestone and dolomite and on a demineralized lignite. The results showed that both calcium minerals captured the gaseous H2S formed under AP-TPR conditions and produced CaS. Consequently the sulfur recovery monitored was too low and the AP-TPR kinetograms were deformed. The study also showed that the influence of dolomite is greater than of limestone. AP-TPR analysis of lignite demineralized and then loaded with calcium ions again showed a clear lowering of sulfur comparable with that of dolomite, but starting at a higher temperature.
