Hydrocracking Process and System Including Separation of Heavy Polynuclear Aromatic Compounds from Recycle by Ionic Liquid and Solids Adsorption |
| abstract |
The process of treatment of the hydrocracking unit bottoms recycle stream, preferably fresh hydrocracker feed, for removing heavy polynuclear aromatic (HPNA) compounds and HPNA precursors is used, alternatively, most of the HPNA compounds The ionic liquid extraction step removes the remaining HPNA compounds following the adsorption step of removing the ions or the first ionic liquid extraction step following the removal of most of the HPNA compounds removes the remaining HPNA compounds. Ionic liquids of the general formula Q + A - are found for use in this process; Organic polar solvents are identified for removal of HPNA compounds in solution. Suitable adsorption is identified for use in packed bed or slurry bed columns operating within a specified temperature and pressure range. |
