选取枣庄煤、东北煤、济宁煤为研究对象，分别测定了三种煤的全硫含量、发热量和热重变化，然后以二硫化碳、丙酮为萃取剂，采用索氏萃取器分别对三种煤进行彻底萃取，得到的萃余煤用双氧水进行氧化，最后用四氢呋喃萃取所得的氧化煤。用FTiR对枣庄、东北、济宁三种原煤、萃余煤、氧化煤进行了分析与比较。FTiR分析表明，无论是萃余煤还是氧化煤其中的物质种类变化不大，但各物质的含量发生很大的变化。
選取棘莊煤、東北煤、濟寧煤為研究對象，分彆測定瞭三種煤的全硫含量、髮熱量和熱重變化，然後以二硫化碳、丙酮為萃取劑，採用索氏萃取器分彆對三種煤進行徹底萃取，得到的萃餘煤用雙氧水進行氧化，最後用四氫呋喃萃取所得的氧化煤。用FTiR對棘莊、東北、濟寧三種原煤、萃餘煤、氧化煤進行瞭分析與比較。FTiR分析錶明，無論是萃餘煤還是氧化煤其中的物質種類變化不大，但各物質的含量髮生很大的變化。

The selection of Zaozhuang coal, the coal, Jining coal as the research object, respectively measured the total sulfur content in coal, heat and thermal weight change of three kinds of coal, and then using carbon disulifde and acetone as extraction agent, by Soxhlet extractor respectively thoroughly extract three kinds of coal, and oxidated the coal residue by hydrogen peroxide, at last extracted the oxidized coal using tetrahydrofuran. analyzed and compared Zaozhuang, northeast, Jining , coal residue oxidized coal with the FTiR, FTiR analysis showed that, whether it is coal residue or changes in the oxidation of coal species is little, but the content of each substance changes a lot.
