Abstract:
A process for the treatment of a hydrocracking unit bottoms recycle stream, and preferably the fresh hydrocracker feed to remove heavy poly-nuclear aromatic (HPNA) compounds and HPNA precursors employs, in the alternative, an adsorption step which removes most of the HPNA compounds followed by an ionic liquid extraction step to remove the remaining HPNA compounds, or a first ionic liquid extraction step which removes most of the HPNA compounds followed by an adsorption step to remove the remaining HPNA compounds. Ionic liquids of the general formula Q + A −  are identified for use in the process; organic polar solvents are identified for removal of the HPNA compounds in solution. Suitable adsorbents are identified for use in packed bed or slurry bed columns that operate within specified temperature and pressure ranges.

Claim (Index 14):
The process of  claim 12  in which the one or more ionic liquids is of the general formula Q + A \u2212 ,\n wherein the A \u2212  ion is selected from the group consisting of halide anions, nitrate, sulfate, phosphate, acetate, haloacetates, tetrafluoroborate, tetrachloroborate, hexafluorophosphate, hexafluoroantimonate, fluorosulfonate, alkyl sulfonates, perfluoroalkyl sulfonates, bis(perfluoroalkylsulfonyl)amides, tris-trifluoromethanesulfononyl methylide of the formula C(CF 3 SO 2 ) 3 \u2014, unsubstituted arenesulfonates, arenesulfonates substituted by halogen or haloalkyl groups, and \n wherein the Q +  ion is an ammonium cation, a phosphonium cation or a sulfonium cation that will form a liquid compound with an A \u2212  ion.
