摘要：
Based on a hydrogen desorption experiment and a comparative experiment of low-temperature coal oxidation performed prior to and after hydrogen desorption, this paper demonstrates the occurrence of hydrogen adsorption in coal at room temperature and reveals that the hydrogen generated in the process of coal oxidation originates from coal oxidation and desorption. The results show that the hydrogen accumulation generated only by coal oxidation and the hydrogen accumulation generated solely by desorption both exhibit a LangmuirEXT1 function equation relationship with temperature. The result of the present research can provide a theoretical basis for the accurate prediction of spontaneous coal combustion and is of great significance to the prevention and control of coal spontaneous combustion in coal mines, industrial coal storage and transportation. © 2014 Kavala Institute of Technology.
