Oxidative treatment with organic peroxides is effective for oxidizing thiophene, which is the main organic sulfur in high-rank coals. The sulfone generated by oxidation of thiophene can be easily removed by pyrolysis at low temperature. However, it is known that the reactivity of thiophenic sulfur to organic peroxides depends significantly on the type of coal. In this study, the relationship between the reactivity of thiophenic sulfur in subbituminous and bituminous coals and coal properties was investigated, and it was confirmed that the reactivity of thiophenic sulfur decreased as the carbon content of coal increased.
