和丰煤的分级热溶研究

Study on Fractionated Thermal Dissolution of Hefeng Coal

新疆和丰煤经由4种不同有机溶剂分级热溶,并利用FTIR和GC/MS测定分析各级热溶产物的成分,研究其化学组成及结构特征。结果表明,分级热溶可以粗分离出煤中的有机化合物。苯的热溶产物中的主要成分是芳烃类物质,其中大部分为稠环芳烃;甲醇、乙醇和异丙醇的热溶产物的主要成分是含氧类物质,其中脂类物质含量最高;在这四种溶剂中,乙醇的热溶产率最高。

Xinjiang Hefeng coal was dissolved with four different organic solvents. The products were analyzed with FTIR and GC/MS and their chemical compositions and structural characteristics were studied. The results showed that the organic compounds in coal can be separated by fractional thermal dissolution.Aromatic compounds are the main components of benzene’s thermal dissolution products, most of which are polycyclic aromatic hydrocarbons. The main components in the thermal dissolution products of methanol, ethanol and isopropyl alcohol are oxygen containing compounds, of which lipid compounds has the highest content. Among the four solvents, ethanol has the highest thermal dissolution yield.
