摘要:

以某石化公司糠醛抽出油为原料,采用复合溶剂二级抽提分离油品中多环芳烃(PCA),制备了芳香基绿色橡胶填充油;对比了三种复合溶剂的应用效果,考察了抽提温度、剂油质量比等操作条件对精制油的收率、PCA质量分数的影响;通过氧化铝吸附色谱法和红外光谱对样品进行了组成分析。结果表明,最佳操作条件为一级溶剂抽提温度70 ℃(剂油质量比5∶1)、二级溶剂抽提温度50 ℃(剂油质量比2∶1);在最佳操作条件下,精制油收率为32.34%,PCA质量分数为2.98%,芳碳率为18.65%,满足欧盟2005/69/EC指令要求;复合溶剂可显著提升溶剂的选择性和溶解性,高效脱除油品中的PCA,并保证较高的产品收率和芳碳率。

Abstract:

Aromatic?based green rubber filler oil is prepared from furfural extraction oil of a petrochemical company by using compound solvents for secondary extraction to separate polycyclic aromatic hydrocarbons present in the oil. Three composite solvents are used for comparison, and the effects of operating conditions, such as extraction temperature and agent?oil mass ratio, on the yield and PCA mass fraction of the refined oil are investigated. A detailed compositional analysis is conducted using the alumina adsorption column method and infrared spectroscopy. The experimental results demonstrate that the optimal operating conditions are primary solvent extraction at 70 ℃ and an agent?oil mass ratio of 5∶1, and secondary solvent extraction at 50 ℃ and an agent?oil mass ratio of 2∶1. The yield of refined oil is 32.34%, the mass fraction of PCA is 2.98%, and the aromatic carbon ratio is 18.65%. These results meet the requirements outlined in EU Directive 2005/69/EC. The results demonstrate that the composite solvent significantly enhances the selectivity and solubility of the solvent, effectively removes PAHs from the oil, and ensures a high product yield and aromatic carbon ratio.
