Abstract:
A process for the treatment of a hydrocracking unit bottoms stream containing heavy poly-nuclear aromatic (HPNA) compounds and/or a fresh hydrocracking feedstock stream containing HPNA precursors to produce coke. The HPNA and/or HPNA precursors are removed from the hydrocracking unit bottoms stream and/or a fresh hydrocracking feedstock stream by solvent washing, and the HPNA and/or HPNA precursors are subjected to delayed coking for the production of coke.
