| Abstract: | A new amide compound solvent was used to separate the aromatic hydrocarbon fraction and the cracking fraction of the recycle oil in a fluid catalytic cracking(FCC) unit.The influences of extraction temperature,ratio of solvent to oil and extraction time on the product yield were investigated.The optimal separating conditions were obtained as follows: extraction temperature 60 ℃,ratio of solvent to oil 2∶1 and extraction time 30 min.Under these conditions,the yield of the extract oil was 79.03% with 87.58% of aromatic hydrocarbons in it.The extract oil can be used as the blending component of the aromatic rubber softener oil.The raffinate oil,with 66.01% of saturated hydrocarbons,exhibits good FCC performance and can be used as FCC feedstock. |
