摘要： 在实验室研究了绥中36-1原油窄馏分CA值与多环芳烃、八种特定芳烃含量之间的关系，发现480℃以上馏分具有生产高芳烃环保橡胶油的优势。自主研发的溶剂抽提逐级精分离工艺新技术在得到相同质量产品的前提下，可以大幅度提高环保橡胶油的收率；新技术的工业应用验证了实验室研究结果，并大幅度降低了产品的生产成本。
关键词: 环保橡胶油, 溶剂抽提, 苯并（a）芘, 多环芳烃
Abstract: The relationship between CA value, PCA and contents of eight kinds of specific aromatics in SZ36-1 vacuum narrow distillate was investigated. Result showed that the distillates (≥480 ℃) have advantages of producing high CA environmental-friendly rubber oils. A new furfural extraction process named gradual fining-separation process was self-developed in which the furfural is injected at upper and lower parts of the tower instead of only at the top position injection. The new process greatly increases the yield of target rubber oils on the premise of the same product quality compared with the traditional technology. The industrial application of the new technology verifies the results of the laboratory research and greatly reduces the production cost of the product.
Key words: environmental friendly rubber oil, solvent extraction, benzopyrene, PCA
