| 摘 要： | 在400℃、30min,7MPa冷氢压条件下两种煤液化结构表明，兖州煤比DECS－6（美国煤）煤更容易液化或共液化，这可能与兖州煤硫含量比较高有关，但DECS－6煤的油收率要高于兖州煤，表明EDCS－6煤容易裂解生成小分子化合物，同时种煤液化油的沸点分布特征基本一致。UV（紫外光谱）特征表明，液化油中单环芳烃主要为烷基取代苯类化合物，二环芳烃组分主要是烷基取代萘类化合物，三环芳烃主要为涉位缩合的菲类化合物，四环芳烃主要为芘、化合物，五环芳烃以苯并芘类化合物为主，而极性化合物可归属为含O、S、N的极性芳香化合物。 |

CHARACTERIZATION OF HEXANE SOLUBLE OILS FROM LIQUEFACTION OF TWO BITUMINOUS COALS |
|
| Abstract: | Two high-volatile subbituminous coals, DECS-6 of US and Yanzhou coal of China, were liquefied or co-liquefied with HDPE or PVC at 400?℃, 30?min under 7?MPa hydrogen. The results show that Yanzhou coal is easier to be liquefied or co-liquefied than DECS-6 coal under the experimental conditions used and the hexane-soluble oil from Yanzhou coal has more low boiling point fractions than that from DECS-6 coal. The aromatics in hexane soluble oils mainly consist of alkylbeneze, alkylnaphthalene, phenanthrene-,pyrene-, chrysene-, and benzopyrene- compounds, the polars mainly compose of compounds containing O， S and N etc. |
| Keywords: | coal liquefaction hexane soluble oils boiling point distribution compound class composition |
