摘要
渣油催化油浆经双溶剂抽提后的抽余油，其饱和烃含量及Ｈ／Ｃ比得到提高，芳烃含量降低，可大大改善催化裂化进料质量，抽出的重质芳烃可作为橡胶软化剂、针状焦及增塑剂等原料。
After double-solvent extraction of slurry from RFCC, the value of H/C and the content of saturated hydrocarbon in the remaining oil were enlarged, the aromatic hydrocarbon content was lowered so the feed stock of RFCC was greatly improved.The heavy aromatic hydrocarbon extracted may be used as softening regent of rubber, needle coke, and elasticity-improving vegeat etc. This technology can bring about remarkable economic profit.
