| Zusammenfassung: | To appropriately evaluate the spontaneous heat generation of coal in a low temperature region by an easy method.SOLUTION: The method for evaluating the spontaneous heat generation of coal includes: an oxidation step of oxidizing coal in a container in an atmosphere containing 18O2 and not containing 16O2: an analysis step of analyzing the atmosphere gas component in the container after the oxidation process; and an evaluation step of evaluating the spontaneous heat generation of the coal on the basis of the amount of carbon dioxide measured by the analysis step.SELECTED DRAWING: Figure 1
【課題】低温域における石炭の自然発熱性を簡便な手法によって適切に評価する。【解決手段】１８Ｏ２を含み１６Ｏ２を含まない雰囲気の容器内で石炭を酸化させる酸化工程と、酸化工程後の容器内の雰囲気ガス成分を分析する分析工程と、分析工程において測定された二酸化炭素量に基づいて、石炭の自然発熱性を評価する評価工程とを含む、石炭の自然発熱性評価方法が提供される。【選択図】図１ |
