| 摘 要： | The influence of solvent formulation, temperature, time and solvent-oil ratio on extract oil yields and aromatics contents were analyzed by four factors and three levels of orthorhombic method with Daqing FCC slurry as feedstock and extraction solvent preparing by N,N-dimethylformamide and anti-extractant. The regressive model of extract oil yields and aromatics contents to solvent formulation, temperature, time and solvent-oil ratio were established. The analysis result by response surface method showed that solvent formulation, temperature and solvent-oil ratio have obvious effect on extraction results and there was interaction between temperature and solvent-oil ratio on aromatics contents when FCC slurry extracted by mixed solvent, but the effect of time was not obvious. The model analysis showed that the optimality conditions for FCC slurry separation by mixed solvent were 2.3 of DMF/ anti-extractant, 62.8℃ of temperature, 3.2 of solvent-oil ratio and 35min of time. The prediction results was well consistent with the verification test.

| Abstract: | The influence of solvent formulation, temperature, time and solvent-oil ratio on extract oil yields and aromatics contents were analyzed by four factors and three levels of orthorhombic method with Daqing FCC slurry as feedstock and extraction solvent preparing by N,N-dimethylformamide and anti-extractant. The regressive model of extract oil yields and aromatics contents to solvent formulation, temperature, time and solvent-oil ratio were established. The analysis result by response surface method showed that solvent formulation, temperature and solvent-oil ratio have obvious effect on extraction results and there was interaction between temperature and solvent-oil ratio on aromatics contents when FCC slurry extracted by mixed solvent, but the effect of time was not obvious. The model analysis showed that the optimality conditions for FCC slurry separation by mixed solvent were 2.3 of DMF/ anti-extractant, 62.8℃ of temperature, 3.2 of solvent-oil ratio and 35min of time. The prediction results was well consistent with the verification test. |
