对用强碱性阴离子交换树脂分离胜利稠油厂的重油催化裂化柴油得到的强酸性和弱酸性组分 ,进行了 IR,UV色谱、元素分析和羟基值的分析 ;又将两组分兑入安定性好的基础柴油中进行了老化动力学研究。结果表明 ,这两种组分主要为酚类化合物 ,还有一定的氮化物和硫化物 ;反应速率 (以柴油 460 nm的吸光度的变化表征 )与两种酸性组分的存在有很大关系 ,反应初始速率对酸性组分的浓度呈近似的一级反应 ,反应有较低的表观活化能。
The analysis of IR, UV, elemental analysis and hydroxyl value of strongly acidic and weakly acidic components obtained from the separation of heavy oil FCC oil from Shengli heavy oil plant by strong basic anion exchange resin was carried out. Stability of the basic diesel in the aging kinetics. The results show that the two components are mainly phenolic compounds, as well as a certain amount of nitrides and sulfides; the reaction rate (characterized by the change of absorbance of diesel at 460 nm) has a great relationship with the existence of two acidic components, The initial reaction rate of acidic components of the concentration was approximately the first reaction, the reaction has a lower apparent activation energy.
