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.
