A series of FE activators were used to intensify Daqing crude oil distillation

which demonstrated that the yield of diesel could be substantially enhanced with activator FE3. From simple distillation

the yield of gasoline was hardly changed while that of diesel could be increased by about 1.0%.In TBP distillation

although no obvious increment was observed for the yield of gasoline

but the yield of light diesel could even be increased by more than 2.0%. Furthermore

diesel was obviously upgraded by this process while gasoline did not deteriorate.
