Abstract
Hydrocracked bottoms fractions are treated to separate HPNA compounds and/or HPNA precursor compounds and produce a reduced-HPNA hydrocracked bottoms fraction effective for recycle. A process for separation of HPNA and/or HPNA precursor compounds from a hydrocracked bottoms fraction of a hydroprocessing reaction effluent comprises contacting the hydrocracked bottoms fraction with heteropoly acid compounds to promote adsorption of HPNAs onto the heteropoly acids and to produce a heteropoly acid treated hydrocracked bottoms fraction, that is recycled within the hydrocracking operation.
