利用压汞法和傅立叶红外光谱分析技术,对研究较少的神府煤样进行了测试与分析。结果表明,孔隙结构会影响煤样自燃的难易,但并不能以此判断煤样是否易燃,还要取决于煤表面活性结构的种类和数量;煤氧复合反应中,早期参与反应的活性基团主要有羟基、甲基、亚甲基及酚醇醚酯的碳氧键等活性结构;含氧官能团在SW煤样的氧化过程中起了较大的作用,说明活性结构在煤氧反应中影响较大,其中含氧官能团在煤炭自燃过程中起着关键性作用。
Using the mercury intrusion method and the Fourier transform infrared spectroscopy technology, the less-studied Shenfu coal samples were tested and analyzed. The results show that pore structure will affect the difficulty of spontaneous combustion of coal samples, but it can not be judged whether flammable coal samples, but also depends on the type and quantity of coal surface active structure; coal-oxygen complex reaction, the early participation in the reaction activity The main functional groups are hydroxyl, methyl, methylene and phenolic ether ester carbon-oxygen bond and other active structures; oxygen-containing functional groups play a greater role in the SW coal sample oxidation process, indicating that the active structure in the coal-oxygen reaction Among them, the oxygen-containing functional groups play a key role in the spontaneous combustion of coal.
