摘要： A two-step hydrocracking process with a distillation step wherein a dividing wall distillation column is used, the dividing wall dividing the lower part of the column into two compartments, located in the section of the column located under the supply of said column with the unconverted effluent resulting from the first hydrocracking step. The distillation column is fed on either side of the vertical dividing wall with the liquid hydrocarbon effluent from the first hydrocracking step and with the liquid hydrocarbon effluent from the second hydrocracking step, allowing the concentration of the HPNAs contained in the effluent from the second hydrocracking step in a specific compartment of the column delimited by the dividing wall and avoiding the dilution of said HPNAs by the unconverted effluent from the first hydrocracking step. The present invention allows purging of purer HPNAs.
