Popis: | Three selected Turkish lignites were pyrolyzed at seven different temperatures between 350 and 950 °C for 7 min. The lignites and their chars were analyzed quantitatively for their total sulphur content and sulphur forms. The alkaline oxide contents of the lignites and selected char samples were determined. Calcium compounds, which prevail in all of the parent lignites, undergo various chemical changes during pyrolysis. The results clearly indicate that both the temperature and the calcium oxide contents affect the behavior of various sulphur forms during pyrolysis. The organic sulphur decomposition and formation is the most difficult to predict. |
