简要介绍了重质馏分油中硫化物的分离富集方法 :氧化还原法和色谱法 ,对两种方法进行了分析评价。氧化还原法通过将极性弱的硫化物氧化成极性强的亚砜或砜后再进行分离、还原 ,其关键在于氧化剂的选择性。利用氧化还原法可得到纯度较高的硫化物 ,但回收率很低 ,且不同硫化物的回收率相差较大。色谱法操作相对比较简单 ,利用具有选择性的配位剂对吸附剂进行改性 ,选择合适的冲洗剂 ,对硫醚、某些含硫多环芳烃具有较高的回收率 ,但难以将一些端位含硫多环芳烃与稠环芳烃分开。色谱法与其他分离方法联合使用 ,能够有效地分离重质馏分油中的硫化物。分离得到的硫化物可利用GC FPD、GS MS等进行定性和定量分析 The methods for the separation and enrichment of sulfide in heavy distillate oil are introduced briefly. The redox method and the chromatographic method are introduced. The two methods are analyzed and evaluated. Redox method by weakly oxidizing the sulfide to a strong polar sulfoxide or sulfone after separation, reduction, the key is the oxidant selectivity. High purity sulfides can be obtained by the redox method, but the recovery rate is very low, and the recoveries of different sulfides are quite different. Chromatography operation is relatively simple, the use of a selective ligand to modify the adsorbent, choose the right rinse, the thioether, some sulfur polycyclic aromatic hydrocarbons have a high recovery, but it is difficult to some End sulfur-containing PAHs are separated from PAHs. Chromatography and other separation methods used in conjunction, can effectively separate heavy oil distillate sulfide. The isolated sulfide can be qualitatively and quantitatively analyzed by GC FPD, GS MS and the like
