Because it is difficult to remove organic sulfur groups from coal, researchers commonly add organicsulfur compounds to model compounds, such as molecular sieves, when analyzing the influence of organic sulfur groups on the spontaneous combustion characteristics of coal (Zhao et al., 2021b).This allows for the simulation of highorganicsulfur coal samples with different sulfur groups and ...
