摘要: 概述了橡胶填充油(简称橡胶油)的分类、发展现状及国内外环保橡胶油的生产工艺和研究进展。环保橡胶油主要有处理芳烃油、重质环烷基油、浅度溶剂抽提油、残余芳烃抽提油以及调合油5大类。以润滑油精制装置副产抽出油、催化裂化油浆、渣油等为原料,环保橡胶油的生产工艺主要有溶剂精制工艺、复合溶剂抽提工艺、加氢精制-溶剂抽提复合工艺、加氢精制工艺等,这些工艺通过选择性脱除原料中的多环芳烃、保留低环芳烃和烷基芳烃来生产环保橡胶油,国内目前存在产能低、产品芳碳率低等问题,影响了环保橡胶油在国内的大规模应用,也影响环保型橡胶轮胎质量的提高。在原有技术方案上开发新的环保橡胶油生产工艺,探索新的加工路线迫在眉睫。

Abstract: The classification, development status, production process and research progress of eco-friendly rubber extender oil (rubber oil) at domestic and overseas were summarized. The rubber oil mainly includes five categories: distillate aromatic extract (TDAE), heavy naphthenic oil (NAP), mildly extract solvate (MES), residual aromatic extract (RAE) and blended oil. Taking by-product extracted oil from lube oil refining unit, FCC slurry and residue, etc. as raw materials, the production process of eco-friendly rubber oil mainly included solvent refining process, double solvent extraction process, hydrorefining-solvent extraction process, etc., these processes produced eco-friendly rubber oil by selective removal of polycyclic aromatic hydrocarbons from raw materials and retention of aromatic hydrocarbons and alkyl-aromatic hydrocarbons with less rings. The main problems were low production volume and low CA of eco-friendly rubber oil, which influenced the large scale application of eco-friendly rubber oil in China and the improvement of the quality of the eco-friendly rubber tire. It was urgent to develop a new production process of eco-friendly rubber oil on the original technical scheme and explore a new processing route.
