The low-temperature pyrolysis of oxygen-containing functional groups in coal plays a vital role in coal spontaneous combustion. This paper conducted isothermal oxidation experiments on raw and pyrolyzed coal samples to investigate the influence of the content of oxygen-containing functional groups, pyrolysis temperature, oxidation temperature, particle size and pyrolysis-oxidation times on the oxidation...
The inorganic salts in coal contain a certain number of metal ions, among which transition metal ions can exert a certain catalytic effect on coal spontaneous combustion by reducing the activation energy of coal oxygen reaction. Therefore, the addition of metal chelating agent in coal will definitely reduce the catalytic effect of metal ions, so as to inhibit coal spontaneous combustion. In this paper,...
