ABSTRACT:
Potential problems associated with the formation of polynuclear aromatic compounds during hydrocracking of residual oils are eliminated by operating at high conversion rates with a high hydrogen concentration followed by a unique separation method. The feed to the final product recovery column is highly vaporized. All of the net bottoms stream of the product recovery column, which is equal to less than 5 vol. percent of the feed, is withdrawn from the process. Only PNA free distillate is recycled.
