摘　　要：通过红外光谱及紫外可见光谱分析了悬浮床加氢裂化助剂对辽河常压渣油沥青质的作用。结果表明,辽河常压渣油沥青质的单元芳香片主要含3~4个芳香环,共轭芳香环的排列形式主要为＂线性排列＂,即渺位缩合。助剂可吸附在沥青质上,其头部磺酸基官能团与沥青质表面的羟基和氨基中的H形成分子间氢键可能是其中的一种作用方式;而尾部的疏水链则能形成稳定层,可将沥青质分子包裹起来,从而能使部分沥青质增溶在正庚烷中。The effect of adjuvant on Liaohe atmospheric residue （LHAR） asphaltene in slurry-bed hydrocracking was studied by means of FT-IR and UV-Vis. The results indicated that the conjugated aromatic ring in unit sheet of LHAR asphaltene contained mainly three or four aromatic rings, which were connected in ＂linear order＂, namely cata-condensed. The adjuvant was adsorbed on the LHAR asphaltene surface through the action of its head group with the hydrogen in hydroxyl and amine groups to form hydrogen bonds. The side chains of adjuvant could form a stable layer to wrap some asphaltene molecules in it, making a part of asphaltene be able to dissolve in heptane.
