The results show that stable organic sulfur is the main s9lfur form in ZY coal. Pyrite can be removed under all the atmospheres in the tests, except for nitrogen at 500℃ 1% O2-N2 atmosphere has strong reactivity to remove the stable organic sulfur in ZY coal, especially at 700℃. Under 1% O2-N2 atmosphere, not only a part of stable organic sulfurs can be decomposed, but also more stable organic sulfur-containing structure can be broken down into less stable one.

结果表明，对于ZY煤而言，黄铁矿和不稳定有机硫除在氮气气氛下500℃时热解不能全部分解外，在其他条件下热解时都可以分解。1%氧气对ZY煤中稳定的有机硫的分解有很强的促进作用，不仅可以脱除稳定的有机硫，还可以使更稳定的有机硫断裂生成次稳定的有机硫，在随后的AP-TPR-MS实验过程中，这部分硫在较低的温度下逸出。

In this study,the organic sulfur compound is decomposed in a oxygen flask;organic sulfur is turned into sulfate sulfur,and then the measure of sulfate is determined by Barium Chromate Spectrophotometer .
