| 摘 要： | 以新疆五彩湾煤为研究对象,进行了煤质和热解分析,考察了溶煤比、反应时间、氢初压和反应温度对其加氢液化效果的影响.结果表明,尽管五彩湾煤惰质组含量高达81.5%,镜质组最大反射率达到0.73%,挥发分低于37%,H/C仅为0.59,但在氢初压仅为6.0MPa,溶煤比1.75和反应时间60min条件下,其最佳液化温度为450℃,油产率和转化率分别达到55.20%和76.76%,仍然具有良好的液化性能.

| Abstract: | CT As a subject of Wucaiwan coal from Xinjiang, its quality characteristics and TG were analyzed, then it was investigated to affect of these four factors such as ratio of mass for solvent to coal, reaction time, initial H2 pressure, and reaction temperature on the coal hydro-liquefaction property. Results show that the optimal reaction temperature is 450 ℃, and oil yield is up to 55.20%, conversion 76.76% at conditions of initial H_2 pressure being 6.0 MPa, ratio of mass for solvent to coal 1.75, reaction time 60 min although the coal sample is soft coal with high inertinite of 81.5%,R_(max)~0=0.73%, V_(daf)<37%, and H/C=0.59. So Wucaiwan coal has good liquefaction performance. |
