中文摘要：

选取安徽褐煤、辽宁褐煤和贵州烟煤三种煤为原料,以油溶性环烷酸钼为催化剂,分别与马瑞常渣（MRAR）、克炼常渣（KAR）以及催化裂化油浆（FCCS）在高压釜内模拟悬浮床加氢共炼反应。结果表明,不同的油体系下,两种褐煤都能达到83%以上的转化率,而对于贵州烟煤,转化率最高的FCCS体系与最低的KAR体系分别为67.75%和50.31%,相差很大。采用FT-IR和SEM分析反应后固体残渣,计算了固体残渣中脂肪族和芳香族中各个基团的相对含量,并对比了不同体系反应后固体残渣的微观形貌。结果表明,KAR体系的固体残渣脂肪链较长,支链化程度高,取代度较低。转化率较高的褐煤反应后固体残渣结构松散,分散度高;转化率较低的烟煤固体残渣随着转化率降低,残渣颗粒逐渐变大,表面更加光滑,板结程度加深。

英文摘要：

Anhui lignite,Liaoning lignite and Guizhou bitumite were co-processed with Murray residue（MRAR）,Karamay residue（KAR）and FCC slurry（FCCS）in an autoclave with molybdenum naphthenate as catalyst,simulating the slurry-phase hydrogenation co-processing.The results showthat for two lignites under different oil systems,the conversion of coal exceeds 83%.However,for Guizhou bitumite,a great difference is observed in the coal conversion between FCCS（67.75%）and KAR（50.31%）for co-processing.The solid residues after co-processing were analyzed by FT-IR and SEM,to determine the relative content of aliphatic and aromatic groups and the micro morphology.It is found that the solid residue derived from the KAR system possesses a lowcontent of CH2/CH3 and a lowsubstitution degree.Moreover,the solid residues obtained from two lignites with high coal conversion exhibit a looser structure and a higher dispersion of solid particles than that from bitumite with a lowcoal conversion.
