摘要: 考察了辽河减渣在吸附分离、酸性溶液萃取和沥青质轻度降解过程中金属铁的分布和转移情况。结果表明,辽河减渣中有近90%的铁富集在胶质和沥青质中,部分铁以侧链较短的环烷酸盐或酚盐形式存在,部分铁连接在沥青质分子的侧链上,或是被包裹在沥青质大分子中。

Abstract: The iron distribution and transfer character in Liaohe VR(vacuum redidue) was studied in the process of its separation and absorption, acid solution extraction and mild chemical oxidation degradation of the asphaltene. The results showed that nearly 90% of iron concentrated in asphaltene and resin fractions. Some iron existed in the formation of carboxylates and phenoxide with short branched chain. Some was linked to the branched chain of asphaltene or included in the macromolecular of asphaltene.
