Abstract: The effects of temperatures and atmospheres on the sulfur transformation during pyrolysis of Liuzhi (LZ) raw coal and the chars (prepared by pyrolysis in a fixed bed reactor) were investigated by AP-TPR-MS combined with chemical analysis. The results show that only a small part of unstable organic sulfur in LZ coal can be removed by pyrolysis in the fixed bed reactor at 500℃ under N2 atmosphere, but pyrite and unstable organic sulfur can be completely removed at 700℃ under N2 atmosphere, and those sulfurs can also be removed at 500℃ under syngas atmosphere. The higher the temperatures, the greater the reactivity of sulfurs with syngas atmosphere, which is very similar to that under H2 atmosphere. However, the sulfur removal is less under 1.0% O2-N2 atmosphere like that under N2 atmosphere.
