Abstract: The environmental rubber oil or FCC feedstock were prepared from FCC slurry using furfural as a extract solvent and petroleum ether as a co-solvent. The influence factors of extract temperature, solvent/oil ratio and extraction stages were investigated by crosscurrent extraction and countercurrent extraction process. The results show that the optimum conditions for single-stage extraction were: extraction temperature of 50 ℃ and solvent/oil ratio of 2.5:1. At this condition the extraction effect becomes better with the extraction stage increasing. At three extraction stages, the polycyclic aromatic hydrocarbons (PCA) content of the refined oil obtained from the two processes were both less than 3% and their aromatic carbon rates were above 10%, meeting the EU requirements for environmental rubber oils. At the same time, the density of the refined oil was dropped below 0.9g/cm3 and the saturated hydrocarbon content reaches above 80%, which was considered to be a qualified FCC feedstock. The yield of the refined oil obtained from the multi-stage countercurrent extraction process reaches above 30%, remarkably higher than the yield obtained from the crosscurrent extraction process.
