摘　　要：以褐煤为原料,在高压釜中考察了褐煤加氢液化的影响因素,研究表明:在同等条件下,加入催化剂后,油气产率、总转化率以及沥青质产率都有不同程度的提高,Fe S催化剂的催化效果要优于Fe SO4催化剂;以水作为液化溶剂时,氢气气氛下的液化油气产率、总转化率以及沥青质产率都要比一氧化碳气氛下的低;以四氢萘作为液化溶剂时,一氧化碳气氛下的液化沥青质产率以及总转化率相比氢气气氛下的高,而油气产率相比氢气气氛下的略低;在氢气气氛下,以四氢萘作为液化溶剂时,总体液化效果要比以水作为液化溶剂时好一些,油气产率及总转化率都有不同程度的提高。In this dissertation, influences of different technical factors on lignite hydro - liquefaction using brown coal as a feedstock were studied in a batch autoclave. Research shows that, Under the same conditions, the addition of catalyst, oil and gas yield, total conversion rate and asphaltene yield have improved to some extent, FeS catalyst catalytic effect is better than FeSO4 catalyst. When the water is used as the liquefied solvent, the liquefied petroleum gas yield, the total conversion rate and the asphaltene yield in the hydrogen atmosphere are lower than those in the carbon monoxide atmosphere. In the case of tetrahydronaphthalene as the liquefied sol- vent, the liquefied asphaltene yield and the total conversion rate in the carbon monoxide atmosphere are higher than those in the hydrogen atmosphere, and the oil and gas yield is slightly lower than that in the hydrogen at- mosphere. When the tetrahydronaphthalene is used as the liquefied solvent in the hydrogen atmosphere, the o- verall liquefaction effect is better than that of the water as the liquefied solvent, and the oil and gas yield and the total conversion rate are improved to some extent.
