Study on the Combined Process of Complexing Denitrifying and FCC Treating Coke Wax Oil.

The coke wax oil is treated by PDN denitriying agent, the rate of removing nitrides is 64. 3% and the yield of the denitrifying wax oil is 97. 3% when dose -- oil ratio is 1 : 100. The evaluation results of small -- scale unit of FCC indicate that the yield of the light fuel oil distillate increased by 7. 65% and the total yield of the liquid fuel oil distillate increased by 9. 80% at the same condition by comparing combined process of the complex denitrifying and FCC with the pure FCC treating. Treating coke wax oil by complexing denitrifying reaction, it decreases the poison of FCC catalysts and increases the yield of the light fuel oil. [ABSTRACT FROM AUTHOR]
